Ultrasonography: current status, challenges, and future directions

Since Ultrasonography was launched as an international peer-reviewed academic journal dedicated to medical ultrasound (US) in January 2014, it has been an honor and privilege for me to serve as the journal’s Honorary Editor [ 1 ]. The purpose of this editorial update is to provide readers with some recent information and to share my views on the journal and its future directions.

During the last 4 years, Ultrasonography has published a total of 160 peer-reviewed articles. In 2017, the Ultrasonography home page had over 85,000 hits per month, with over 2,300 downloads of manuscripts from 115 different countries per month. In 2016, Ultrasonography demonstrated an increase in the number of citations by authors throughout the world, and the estimated impact factor of Ultrasonography reached 2.075 [ 2 ], as it has continued to attract more and more international readers. Consequently, Ultrasonography became indexed by the Web of Science’s new Emerging Source Citation Index (ESCI) in November 2016 [ 2 ] and by SCOPUS in September 2017, marking it as one of the leading global journals in the field of medical US.

The aim of Ultrasonography is to provide up-to-date information on new diagnostic concepts and technical developments, as well as to publish well-designed reviews of contemporary issues in patient care in the field of medical US. As the Honorary Editor of Ultrasonography , I am aware of the editor’s tremendous responsibility in guiding the publication to fulfill the aims of Ultrasonography and of how important the roles of the authors, reviewers, and readers are for a journal to be successful.

Those of us who are involved in the journal’s publication have the great responsibility to provide an effective means to disseminate the original work of the authors as well as to provide timely, high-quality research to readers. We will continue to promote and publish high-quality peer-reviewed research. We also plan to invite internationally renowned scholars to submit reviews of the latest research and introductions to innovative new technologies to enhance the quality of the content and to attract a larger international readership. Original articles that advance the science of US will remain the centerpiece of the journal, while Pictorial Essays, Technical Notes, and Perspectives will continue to be published. Sonologists and US-related specialists are encouraged to submit their most promising research results to Ultrasonography . We will continue to provide high-quality editing and publishing services without cost, and there will be no fees for submissions or for the publication process.

A quality publication must have capable, fair, and considerate reviewers, as well as outstanding authors and manuscripts. The adoption of a double-blind peer review process and an open-access policy will enable Ultrasonography to fulfill its obligation to publication ethics; each article must also comply with our editorial standards for quality and ethics. We have thus established an Editorial Board composed of internationally renowned scholars and scientists to meet global standards for the process of peer-reviewing submitted manuscripts. We are grateful to the many reviewers and editorial members who volunteer their time and effort to ensure the quality of the journal’s content. The speed of publication is also important for the journal’s success. We have established a state-of-the-art electronic manuscript submission, review, and electronic publishing system, and we make our best effort to complete the review process as soon as possible, ideally within 4 weeks of receiving a manuscript submission.

Going forward, I believe Ultrasonography will be a useful and valuable international journal covering recent advances in US for every US-related specialist. I look forward to receiving a wide range of submissions and contributions from basic and clinical researchers throughout the world.

Open Access is an initiative that aims to make scientific research freely available to all. To date our community has made over 100 million downloads. It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. As PhD students, we found it difficult to access the research we needed, so we decided to create a new Open Access publisher that levels the playing field for scientists across the world. How? By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers.

We are a community of more than 103,000 authors and editors from 3,291 institutions spanning 160 countries, including Nobel Prize winners and some of the world’s most-cited researchers. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too.

Please login to bookmark

Introduction

A thesis or dissertation, as some people would like to call it, is an integral part of the Radiology curriculum, be it MD, DNB, or DMRD. We have tried to aggregate radiology thesis topics from various sources for reference.

Not everyone is interested in research, and writing a Radiology thesis can be daunting. But there is no escape from preparing, so it is better that you accept this bitter truth and start working on it instead of cribbing about it (like other things in life. #PhilosophyGyan!)

Start working on your thesis as early as possible and finish your thesis well before your exams, so you do not have that stress at the back of your mind. Also, your thesis may need multiple revisions, so be prepared and allocate time accordingly.

Tips for Choosing Radiology Thesis and Research Topics

Keep it simple silly (kiss).

Retrospective > Prospective

Retrospective studies are better than prospective ones, as you already have the data you need when choosing to do a retrospective study. Prospective studies are better quality, but as a resident, you may not have time (, energy and enthusiasm) to complete these.

Choose a simple topic that answers a single/few questions

Original research is challenging, especially if you do not have prior experience. I would suggest you choose a topic that answers a single or few questions. Most topics that I have listed are along those lines. Alternatively, you can choose a broad topic such as “Role of MRI in evaluation of perianal fistulas.”

You can choose a novel topic if you are genuinely interested in research AND have a good mentor who will guide you. Once you have done that, make sure that you publish your study once you are done with it.

Get it done ASAP.

In most cases, it makes sense to stick to a thesis topic that will not take much time. That does not mean you should ignore your thesis and ‘Ctrl C + Ctrl V’ from a friend from another university. Thesis writing is your first step toward research methodology so do it as sincerely as possible. Do not procrastinate in preparing the thesis. As soon as you have been allotted a guide, start researching topics and writing a review of the literature.

At the same time, do not invest a lot of time in writing/collecting data for your thesis. You should not be busy finishing your thesis a few months before the exam. Some people could not appear for the exam because they could not submit their thesis in time. So DO NOT TAKE thesis lightly.

Do NOT Copy-Paste

Reiterating once again, do not simply choose someone else’s thesis topic. Find out what are kind of cases that your Hospital caters to. It is better to do a good thesis on a common topic than a crappy one on a rare one.

Books to help you write a Radiology Thesis

Event country/university has a different format for thesis; hence these book recommendations may not work for everyone.

What is medical ultrasound?

How does it work, what is ultrasound used for, are there risks, what are examples of nibib-funded projects using ultrasound.

Medical ultrasound falls into two distinct categories: diagnostic and therapeutic.

Diagnostic ultrasound can be further sub-divided into anatomical and functional ultrasound. Anatomical ultrasound produces images of internal organs or other structures. Functional ultrasound combines information such as the movement and velocity of tissue or blood, softness or hardness of tissue, and other physical characteristics, with anatomical images to create “information maps.” These maps help doctors visualize changes/differences in function within a structure or organ.

Therapeutic ultrasound also uses sound waves above the range of human hearing but does not produce images. Its purpose is to interact with tissues in the body such that they are either modified or destroyed. Among the modifications possible are: moving or pushing tissue, heating tissue, dissolving blood clots, or delivering drugs to specific locations in the body. These destructive, or ablative, functions are made possible by use of very high-intensity beams that can destroy diseased or abnormal tissues such as tumors. The advantage of using ultrasound therapies is that, in most cases, they are non-invasive. No incisions or cuts need to be made to the skin, leaving no wounds or scars.

Ultrasound waves are produced by a transducer, which can both emit ultrasound waves, as well as detect the ultrasound echoes reflected back. In most cases, the active elements in ultrasound transducers are made of special ceramic crystal materials called piezoelectrics. These materials are able to produce sound waves when an electric field is applied to them, but can also work in reverse, producing an electric field when a sound wave hits them. When used in an ultrasound scanner, the transducer sends out a beam of sound waves into the body. The sound waves are reflected back to the transducer by boundaries between tissues in the path of the beam (e.g. the boundary between fluid and soft tissue or tissue and bone). When these echoes hit the transducer, they generate electrical signals that are sent to the ultrasound scanner. Using the speed of sound and the time of each echo’s return, the scanner calculates the distance from the transducer to the tissue boundary. These distances are then used to generate two-dimensional images of tissues and organs.

During an ultrasound exam, the technician will apply a gel to the skin. This keeps air pockets from forming between the transducer and the skin, which can block ultrasound waves from passing into the body.

Diagnostic ultrasound. Diagnostic ultrasound is able to non-invasively image internal organs within the body. However, it is not good for imaging bones or any tissues that contain air, like the lungs. Under some conditions, ultrasound can image bones (such as in a fetus or in small babies) or the lungs and lining around the lungs, when they are filled or partially filled with fluid. One of the most common uses of ultrasound is during pregnancy, to monitor the growth and development of the fetus, but there are many other uses, including imaging the heart, blood vessels, eyes, thyroid, brain, breast, abdominal organs, skin, and muscles. Ultrasound images are displayed in either 2D, 3D, or 4D (which is 3D in motion).

Functional ultrasound. Functional ultrasound applications include Doppler and color Doppler ultrasound for measuring and visualizing blood flow in vessels within the body or in the heart. It can also measure the speed of the blood flow and direction of movement. This is done using color-coded maps called color Doppler imaging. Doppler ultrasound is commonly used to determine whether plaque build-up inside the carotid arteries is blocking blood flow to the brain.

Another functional form of ultrasound is elastography, a method for measuring and displaying the relative stiffness of tissues, which can be used to differentiate tumors from healthy tissue. This information can be displayed as either color-coded maps of the relative stiffness; black-and white maps that display high-contrast images of tumors compared with anatomical images; or color-coded maps that are overlayed on the anatomical image. Elastography can be used to test for liver fibrosis, a condition in which excessive scar tissue builds up in the liver due to inflammation.

Ultrasound is also an important method for imaging interventions in the body. For example, ultrasound-guided needle biopsy helps physicians see the position of a needle while it is being guided to a selected target, such as a mass or a tumor in the breast. Also, ultrasound is used for real-time imaging of the location of the tip of a catheter as it is inserted in a blood vessel and guided along the length of the vessel. It can also be used for minimally invasive surgery to guide the surgeon with real-time images of the inside of the body.

Therapeutic or interventional ultrasound. Therapeutic ultrasound produces high levels of acoustic output that can be focused on specific targets for the purpose of heating, ablating, or breaking up tissue. One type of therapeutic ultrasound uses high-intensity beams of sound that are highly targeted, and is called High Intensity Focused Ultrasound (HIFU). HIFU is being investigated as a method for modifying or destroying diseased or abnormal tissues inside the body (e.g. tumors) without having to open or tear the skin or cause damage to the surrounding tissue. Either ultrasound or MRI is used to identify and target the tissue to be treated, guide and control the treatment in real time, and confirm the effectiveness of the treatment. HIFU is currently FDA approved for the treatment of uterine fibroids, to alleviate pain from bone metastases, and most recently for the ablation of prostate tissue. HIFU is also being investigated as a way to close wounds and stop bleeding, to break up clots in blood vessels, and to temporarily open the blood brain barrier so that medications can pass through.

Diagnostic ultrasound is generally regarded as safe and does not produce ionizing radiation like that produced by x-rays. Still, ultrasound is capable of producing some biological effects in the body under specific settings and conditions. For this reason, the FDA requires that diagnostic ultrasound devices operate within acceptable limits. The FDA, as well as many professional societies, discourage the casual use of ultrasound (e.g. for keepsake videos) and recommend that it be used only when there is a true medical need.

The following are examples of current research projects funded by NIBIB that are developing new applications of ultrasound that are already in use or that will be in use in the future:

3D printing through the skin : Researchers at Duke University have developed a method to 3D print biocompatible structures through thick, multi-layered tissues. The approach entails using focused ultrasound to solidify a special ink that has been injected into the body to repair bone or repair soft tissues, for example. Initial experiments in animal tissue suggest the method could turn highly invasive surgical procedures into safer, less invasive ones.

Inducing a hibernation-like state : Researchers at Washington University in St. Louis used ultrasound waves directed into the brain to lower the body temperature and metabolic rates of mice, inducing a hibernation-like state, called torpor. The researchers replicated some of these results in rats, which, like humans, don’t naturally enter torpor. Inducing torpor could help minimize damage from stroke or heart attack and buy precious time for patients in critical care.

High-quality imaging at home : Brigham and Women’s Hospital researchers compared ultrasound scans acquired by experts with those taken by inexperienced volunteers, finding little difference in the image quality of the two groups. The unconventional approach of having patients take ultrasound images of themselves at home and share them with healthcare professionals could allow for remote monitoring and reduce the need for hospitalization.

Ultrasound offers a new way to perform deep brain stimulation

Press contact :.

Previous image Next image

Deep brain stimulation, by implanted electrodes that deliver electrical pulses to the brain, is often used to treat Parkinson’s disease and other neurological disorders. However, the electrodes used for this treatment can eventually corrode and accumulate scar tissue, requiring them to be removed.

MIT researchers have now developed an alternative approach that uses ultrasound instead of electricity to perform deep brain stimulation, delivered by a fiber about the thickness of a human hair. In a study of mice, they showed that this stimulation can trigger neurons to release dopamine, in a part of the brain that is often targeted in patients with Parkinson’s disease.

“By using ultrasonography, we can create a new way of stimulating neurons to fire in the deep brain,” says Canan Dagdeviren, an associate professor in the MIT Media Lab and the senior author of the new study. “This device is thinner than a hair fiber, so there will be negligible tissue damage, and it is easy for us to navigate this device in the deep brain.”

In addition to offering a potentially safer way to deliver deep brain stimulation, this approach could also become a valuable tool for researchers seeking to learn more about how the brain works.

MIT graduate student Jason Hou and MIT postdoc Md Osman Goni Nayeem are the lead authors of the paper, along with collaborators from MIT’s McGovern Institute for Brain Research, Boston University, and Caltech. The study appears today in Nature Communications .

Deep in the brain

Dagdeviren’s lab has previously developed wearable ultrasound devices that can be used to deliver drugs through the skin or perform diagnostic imaging on various organs . However, ultrasound cannot penetrate deeply into the brain from a device attached to the head or skull.

“If we want to go into the deep brain, then it cannot be just wearable or attachable anymore. It has to be implantable,” Dagdeviren says. “We carefully customize the device so that it will be minimally invasive and avoid major blood vessels in the deep brain.”

Deep brain stimulation with electrical impulses is FDA-approved to treat symptoms of Parkinson’s disease. This approach uses millimeter-thick electrodes to activate dopamine-producing cells in a brain region called the substantia nigra. However, once implanted in the brain, the devices eventually begin to corrode, and scar tissue that builds up surrounding the implant can interfere with the electrical impulses.

The MIT team set out to see if they could overcome some of those drawbacks by replacing electrical stimulation with ultrasound. Most neurons have ion channels that are responsive to mechanical stimulation, such as the vibrations from sound waves, so ultrasound can be used to elicit activity in those cells. However, existing technologies for delivering ultrasound to the brain through the skull can’t reach deep into the brain with high precision because the skull itself can interfere with the ultrasound waves and cause off-target stimulation.

“To precisely modulate neurons, we must go deeper, leading us to design a new kind of ultrasound-based implant that produces localized ultrasound fields,” Nayeem says. To safely reach those deep brain regions, the researchers designed a hair-thin fiber made from a flexible polymer. The tip of the fiber contains a drum-like ultrasound transducer with a vibrating membrane. When this membrane, which encapsulates a thin piezoelectric film, is driven by a small electrical voltage, it generates ultrasonic waves that can be detected by nearby cells.

“It’s tissue-safe, there’s no exposed electrode surface, and it’s very low-power, which bodes well for translation to patient use,” Hou says.

In tests in mice, the researchers showed that this ultrasound device, which they call ImPULS (Implantable Piezoelectric Ultrasound Stimulator), can provoke activity in neurons of the hippocampus. Then, they implanted the fibers into the dopamine-producing substantia nigra and showed that they could stimulate neurons in the dorsal striatum to produce dopamine.

“Brain stimulation has been one of the most effective, yet least understood, methods used to restore health to the brain. ImPULS gives us the ability to stimulate brain cells with exquisite spatial-temporal resolution and in a manner that doesn’t produce the kind of damage or inflammation as other methods. Seeing its effectiveness in areas like the hippocampus opened an entirely new way for us to deliver precise stimulation to targeted circuits in the brain,” says Steve Ramirez, an assistant professor of psychological and brain sciences at Boston University, and a faculty member at B.U.’s Center for Systems Neuroscience, who is also an author of the study.

A customizable device

All of the components of the device are biocompatible, including the piezoelectric layer, which is made of a novel ceramic called potassium sodium niobate, or KNN. The current version of the implant is powered by an external power source, but the researchers envision that future versions could be powered a small implantable battery and electronics unit.

The researchers developed a microfabrication process that enables them to easily alter the length and thickness of the fiber, as well as the frequency of the sound waves produced by the piezoelectric transducer. This could allow the devices to be customized for different brain regions.

“We cannot say that the device will give the same effect on every region in the brain, but we can easily and very confidently say that the technology is scalable, and not only for mice. We can also make it bigger for eventual use in humans,” Dagdeviren says.

The researchers now plan to investigate how ultrasound stimulation might affect different regions of the brain, and if the devices can remain functional when implanted for year-long timescales. They are also interested in the possibility of incorporating a microfluidic channel, which could allow the device to deliver drugs as well as ultrasound.

In addition to holding promise as a potential therapeutic for Parkinson’s or other diseases, this type of ultrasound device could also be a valuable tool to help researchers learn more about the brain, the researchers say.

“Our goal to provide this as a research tool for the neuroscience community, because we believe that we don’t have enough effective tools to understand the brain,” Dagdeviren says. “As device engineers, we are trying to provide new tools so that we can learn more about different regions of the brain.”

The research was funded by the MIT Media Lab Consortium and the Brain and Behavior Foundation Research (BBRF) NARSAD Young Investigator Award.

Evaluation of U-Nets for object segmentation in ultrasound images

Jun 20, 2024, 2:16 PM

Rui Wang, Katelyn Craft, Elisa Holtzman, Hannah Mason, Christopher Khan, Brett Byram, Jason Mitchell, and Jack H. Noble. “ Evaluation of U-Nets for Object Segmentation in Ultrasound Images .” Proceedings of SPIE Medical Imaging 2024: Ultrasonic Imaging and Tomography, vol. 12932, 129321G, 2024, San Diego, California, United States.

Ultrasound imaging is widely used in medicine due to its safety and cost-effectiveness compared to other methods. However, its quality can vary depending on tissue properties and depth. In this study, researchers tested deep learning techniques to create 3D models of objects imaged with ultrasound. They used three versions of the 3D U-Net model, each trained with different scenarios. The models performed well on specific categories of objects they were trained on but struggled with new categories. Researchers also looked into dual-task autoencoding to improve performance across different object types. These findings set a foundation for further improving the U-Net model to handle a broader range of ultrasound imaging tasks, potentially enhancing visualization and accuracy in medical applications.

Medical ultrasound represented by ultrasound imaging is generally believed to be well-known area in research, because ultrasound imaging systems has been widely distributed and actively used in the world since the 1960s. The annual world-wide use of ultrasound imaging in practice is already over billions and all pregnant women have been screened with ultrasound in some countries, such as Germany, Norway, Iceland, and Austria for years [ 1 ]. In industry, not only portable systems were available since the early 2000s, but also wireless ultrasound imaging transducers cooperating with tablet PCs were introduced in the early 2010s. Accordingly, ultrasound in medicine has been believed relatively low-tech and obsolete research field to general audience.

However, medical ultrasound has been one of the most active research areas for last 20 years and numerous outstanding break-troughs has been reported in both diagnostic and therapeutic ultrasound. In ultrasound imaging, elastography, ultrasound contrast agent imaging [ 2 ], super resolution imaging, and 2D array transducer are noteworthy. Elastic property of a given tissue can be critical for cancer diagnosis of a certain fibrous tumor and evaluation of vulnerable plaque in artery during stent implantation [ 3 ]. However, elastic characteristics cannot be clearly visualized in general ultrasound images. In order to quantitative measure of elasticity, radiation force which provides controlled deformation force on target tissue was implemented by ultrasound imaging transducer and speckle tracking algorithm which provides means of local tissue position tracking up to tens of micrometers was developed. These technologies later combined with a high frame late ultrasound imaging system whose frame late can reach up to 10,000/s and presented high resolution quantitative elastography [ 4 , 5 ]. On the other hand, super resolution imaging was achieved by simply tracking microbubbles in blood vessel with a high frame late system introduced above [ 6 ]. Since a single microbubble can be counted as a scatterer whose resolution is several orders higher than the point spread function of ultrasound system, the resultant images can show us excellent vasculature networks in deeply located organ. In order to expand these new technologies of ultrasound imaging in 3D, 2D array transducer is required, so that micro-machined transducers were also developed [ 7 ].

While researches and developments in ultrasound imaging area have been outstanding recently, novel approaches in therapeutic ultrasound have been equally impressive if not superior. 2D phased array transducers in high intensity focused ultrasound (HIFU) not only facilitate fast abdominal cancer treatment [ 8 ] but also enable to treat brain diseases without craniotomy or burr hole trephination. With the help of MRI guidance for brain treatment, ultrasound technology brought non-invasive means for selective treatment brain related disease and the result from clinical trials in tremor patients was exceptionally promising [ 9 , 10 ]. Spatially targeted drug delivery with ultrasound and microbubbles is another hot issue in medical ultrasound. Ultrasound is time varying acoustic pressure field and microbubbles in ultrasound field oscillate and/or rapidly collapse. These bubble activities are generally defined as acoustic cavitation. If cavitation activities occur nearby biological boundary which acts as a barrier, the barrier function of the boundary is temporally disturbed. Combined with the spatially selective nature of focused ultrasound, ultrasound mediated spatially targeted drug delivery with microbubbles has been a main research topic over last 20 years. As for the application, ultrasound mediated drug delivery through blood brain barrier (BBB) has been most successful in animal model experiments [ 11 , 12 ]. Although BBB opening is caught attention from general public, ultrasound mediated drug delivery has also been widely researched for the targeted cancer treatment in both body and brain. The last noteworthy ultrasound therapy is histotripsy [ 13 ]. This term is antonym to lithotripsy which indicates destruction of calcified targets such as kidney stone. In histotripsy, the target soft tissue is completely pulverized with multiple cavitations induced by repetitive high amplitude ultrasound pulses without cavitation seeds. This technique provides clear cut lines between treated tissue and surrounding tissue unlike HIFU which generally uses thermal effect and has smeared boundary. Accordingly, histotripsy can be an extremely selective tool for cancer treatment.

Although it is not mentioned above, there are additional ultrasound related research areas such as photoacoustics and ultrasound neuromodulation. Photoacoustic imaging (PAI) uses a pulsed laser excitation to generate sound in body and receives the signal with an ultrasound transducer. Since the focal spot size of laser is multiple orders smaller than that of ultrasound beam, the image resolution is phenomenally higher compared to general ultrasound images. PAI can be also easily implemented with ultrasound imaging since they can share the identical transducer [ 14 ]. Additionally, most of algorithms developed for ultrasound imaging over the decades can be directed translated to PAI and ultrasound elastography could be one of the top candidates. While most of the introduced topics have at least a specific application, ultrasound neuromodulation is in a still early stage of research to determine a certain definitive application. Since the middle of 2000s, both excitational and inhibitive neural activities induced by low intensity ultrasound have been demonstrated in the number of animal models [ 15 ]. Although the underlying mechanism has not yet been clearly understood, many of researchers expect that ultrasound neuromodulation might replace transcranial magnetic stimulation (TMS).

As described above, medical ultrasound field is boarder than general perception at least in research area. Hence, this special issue is designed to bring in various ultrasound-related topics in medicine. We also tried to invite both engineering and medical sectors to include different perspectives in medical ultrasound. Although we could not cover all the topics mentioned above, articles in this special issue will extend the general perception and will provide broader understanding on ultrasound research field.

Finally, we guest editors would like to express our gratitude to the authors who contributed in this special issue in the field of medical ultrasound.

Musculoskeletal ultrasonography has become an increasingly valuable tool as a complement to the physical exam in rheumatology practice. Its point-of-care access, low cost, safety, portability, and reliability in trained hands, make this technique especially useful in patients with inflammatory arthritis. Growing evidence has demonstrated the value of musculoskeletal ultrasound in the detection of inflammatory and structural changes in patients with joint pain without obvious joint swelling, in differentiating various inflammatory diagnoses, in the monitoring of inflammatory arthritis, and interventional procedures. The potential role of ultrasound guiding treat-to-target strategies or tapering treatment in inflammatory arthritis requires further research. However, musculoskeletal ultrasound can also have pitfalls and limitations that a clinician should be aware of.

Ultrasound beam triggers 'nanodroplets' to deliver drugs at exactly the right spot

by Frontiers

Conventional drug delivery is often like cracking a nut with a sledgehammer. Whether the drug is swallowed, injected, inhaled, or absorbed through the skin, it ultimately diffuses to most parts of the body, including those where it isn't needed—or where it might even cause harm.

But what if the delivery could be targeted at exactly the right spot? This would allow the total dose to be dramatically lower, thus minimizing side-effects.

Now, scientists from the US have found a way to perfect a promising, emerging method that does just that. With their new protocol, the method is made both safe and efficient for the first time, hopefully paving the way for first-in-human trials. The results are published in Frontiers in Molecular Biosciences .

"Here we show a method to deliver drugs to specific areas of the body where they are needed. We do so using ultrasound waves , which trigger drug release from circulating nanocarriers when focused on the target," said Matthew G Wilson, a graduate research assistant at the University of Utah, and the study's first author. "We developed a method to produce stable nanocarriers repeatably, and identified ultrasound parameters that can activate them."

Nanoengineered droplets

The nanocarriers are minuscule droplets, between 470 and 550 nanometers across, with a hollow outer shell composed of polymer molecules. These polymers have two distinct ends: a hydrophilic one, which mixes well with watery solutions like blood and which faces outward, and a hydrophobic one that doesn't mix with water and which faces inwards.

Within the shell is an inner core of hydrophobic perfluorocarbons, molecules that consist mostly of fluorine and carbon, and that are mixed with an equally hydrophobic drug of interest. The shells keep the cores apart, preventing them from coalescing into a single droplet, and form a barrier against the immune system. The effect is much like mayonnaise, where proteins from eggs form droplets of encapsulated oils, where otherwise the oil and water would separate completely.

To release the drug, the researchers played back an ultrasound—a sound wave with a frequency beyond the upper limit of human hearing—of 300 or 900 kilohertz. The beam of ultrasound can be steered across three dimensions, to focus on a desired area within the body that is only a few millimeters across.

The ultrasound is thought to cause the perfluorocarbons to expand, stretching out the droplet's shell and making it more permeable to the drug, which then diffuses out to the organs, tissues, or cells where it is required.

The researchers compared the efficiency of delivery of a representative drug—the anesthetic and sedative propofol—between three different perfluorocarbons, perfluoropentane (PFP), decafluoropentane (DFP), and perfluorooctylbromide (PFOB). The ultrasound was delivered to the nanodroplets in vitro, in 60 pulses of 100 milliseconds over one minute.

Reaching the boiling point

The results showed that the balance between stability of the nanodroplets and the efficiency of delivery was optimal for PFOB cores.

"Previous studies have focused on perfluorocarbons with low boiling points—usually lower than the human body temperature. We found that droplets with a PFOB core, which has a boiling point of 142 °C, are much more stable over time," explained Wilson.

"Despite its high boiling point, PFOB can achieve similar levels of drug release when low-frequency ultrasound of 300 kilohertz is applied. The ultrasound frequency turned out to be a critical factor in our study."

To test for safety, the researchers injected a single long-tailed macaque with six doses of PFOB-based nanodroplets at one-week intervals, and monitored the evolution of a range of blood biomarkers for liver, kidney, and immune response function. This experiment, which had been approved by University of Utah Institutional Animal Care and Use Committee, showed that the nanodroplets were well tolerated, with no detectable side effects. These experiments must be replicated in microdosing or Phase I trials on human volunteers.

The authors also published their protocol for the production of the nanodroplets as open science, so other research groups can learn directly from their findings.

"The method we developed can be applied to any of a variety of conditions depending on the drug used. For psychiatric applications, localized delivery of propofol could be used as a diagnostic tool to identify brain regions causally involved in disorders for individual patients. For more lasting treatment, ketamine delivery could be a potent method to rewire neural circuits ," concluded Wilson's academic supervisor, Dr. Jan Kubanek, an assistant professor at the University of Utah, and the study's senior author.

Combining mammography with ultrasound tomography improves cancer detection

Combining full-field digital mammography with ultrasound tomography can improve breast cancer detection and be helpful in imaging dense breasts, according to research published June 18 in Radiology .

A team led by Mary Yamashita, MD, from the University of Southern California in Los Angeles, found that the combined method outperformed full-field digital mammography by itself, including having higher sensitivity for BI-RADS 4 lesions and higher specificity for BI-RADS 3 lesions.

“Our study suggests ultrasound tomography can be another supplemental screening tool,” Yamashita and colleagues wrote.

Previous studies suggest that women with dense breasts benefit from supplemental ultrasound imaging. However, ultrasound has low specificity and automated breast ultrasound (ABUS) prolongs interpretation time.

However, ultrasound tomography provides four coronal volumetric image sequences of B mode and quantitative tissue characterization information. This includes tissue stiffness, speed of sound, and attenuation.

“By merging reflection images with these parameters, ultrasound tomography can potentially differentiate cancer from normal tissue or benign disease in women with dense breasts,” the researchers wrote.

Yamashita and colleagues evaluated the performance of ultrasound tomography combined with full-field digital mammography and compared it with that of full-field digital mammography alone for screening women with dense breasts.

The study included data collected between 2017 and 2019 from 140 women who underwent both modalities at 10 centers as part of a prospective case collection registry. For the study, 32 radiologists who are qualified under the Mammography Quality Standards Act independently evaluated full-field digital mammograms followed immediately by mammography plus ultrasound tomography for suspicious findings and assigned a BI-RADS category.

Of the 140 women (average age, 56 years), 36 had breast cancer and 104 did not.

The team reported that the combined approach demonstrated superior performance compared with mammography alone. Additionally, combining mammography with ultrasound tomography led to superior sensitivity in BI-RADS 4 lesions and superior specificity in BI-RADS 3 lesions.

The radiologists performed 4,480 readings using both the combined approach and mammography alone. Of the readings, 4,475 combined approach readings and 4,332 mammography-alone readings took less than 30 minutes to complete.

The team reported that among images read in 30 minutes or less, the median reading time was 3.4 minutes for mammography plus ultrasound tomography and 1.2 minutes for mammography alone. However, for mammography plus ultrasound tomography, images with normal findings had a median reading time of 3.2 minutes compared to 3.9 minutes for mammography alone.

The study authors wrote that while their results indicate ultrasound tomography’s utility in this area, more studies are needed to evaluate the modality’s benefits. This includes determining whether ultrasound tomography can improve cancer detection without increasing the number of benign biopsies.

In an accompanying editorial, Ritse Mann, MD, PhD, from Radboud University Medical Center in Nijmegen, the Netherlands, wrote that the results demonstrate ultrasound tomography being “at best on par” with handheld ultrasound and automated breast ultrasound. This includes allowing detection of some additional cancers at the price of a substantial increase in the number of false-positive findings.

“It seems that ultrasound tomography may be a new implementation of ultrasound, but it unfortunately yields old results,” Mann wrote.

Mann added that it remains to be seen whether “the promise of ultrasound can ever be delivered and whether ultrasound tomography has a role in that.”

Hypersonic research topics.

Shannon Eichorn

System-level design and analysis, propulsion technologies, vehicle technologies, high temperature materials.

The Hypersonic Technology project is divided into four research topic areas. The first research topic is system-level design, analysis, and validation, which explores the impacts of technologies on vehicle performance. The second and third topics focus more specifically on propulsion technologies and vehicle technologies enabling hypersonic flight. The fourth topic area explores material technology that can survive and be reused in high-temperature hypersonic flight.

The System-Level Design, Analysis, and Validation research topic (RT-1) investments are focused on computational tool development and validation for hypersonic propulsion and vehicle system analysis methods including uncertainty quantification. RT-1 coordinates and performs definitive systems analysis studies to clarify the potential benefits of hypersonic vehicles and technologies for both high-speed civilian travel and space access and will use these studies to drive a technology portfolio focused on reusability, affordability, and reliability.

The Propulsion Technologies research topic (RT-2) focuses on turboramjet, ramjet, integrated combined-cycle, dual-mode, and scramjet propulsion systems and associated propulsive mode transitions, combustor operability, fuels, controls, and sensors. RT-2 develops computational fluid dynamic technologies to enable predictive simulations of these systems.

The Vehicle Technologies research topic (RT-3) investments focus on understanding aerodynamic and aerothermodynamic phenomena, such as high-speed boundary-layer transition and shock-dominated flows, to further technologies that improve aerodynamic performance as well as reduce aerodynamic heating.

The High Temperature Durable Materials research topic (RT-4) investments focus on advanced propulsion and vehicle materials research. Due to the operating conditions of hypersonic vehicles, most of the structures and materials are shared between propulsion and vehicle components, which include aeroshell, control surface, leading edge, propulsion, and sealing concepts. RT-4 examines the design and evaluation of potential structure and material concepts through component development and testing under relevant environments. In addition, because of the extreme environments the materials and structures must endure, RT-4 also includes development of advanced thermal and structural measurement methods.
