Vaccinations, blood tests, or IVs – it’s fair to say that no child likes a needle. So, when it comes to the jab, a light touch and a caring approach is incredibly welcomed – both by the child and the parent. Now, world-first research from the University of South Australia shows that while many children suffer distress, new ultrasound-guided techniques could provide much-needed reprieve.
Suvranu De, dean of the FAMU-FSU College of Engineering, is leading a five-year, $1.3 million cooperative research agreement with the U.S. Army that will use ultrasound and artificial intelligence to investigate the characteristics and healing trajectory of burn wounds, leading to faster diagnosis and improved recovery.
Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the brain.

At the 184th ASA Meeting, Ashley Alva of the Georgia Institute of Technology will describe how attaching microbubbles to macrophages, a type of white blood cell, can create high-resolution and sensitive tracking images useful for disease diagnosis. Because of the attached microbubbles, the cells sent back an echo when hit with ultrasound, which is nonionizing and noninvasive and has great depth of penetration. This allowed the team to visualize the macrophages in vivo with high resolution and sensitivity. Visualizing macrophages in vivo could also provide a powerful tool for understanding immune responses and monitoring therapeutic efficacy.

In the procedure, the physician uses a handheld transducer placed on the skin to direct ultrasound waves towards the stone. The ultrasound can then be used to move and reposition the stones to promote their passage, a process called ultrasound propulsion, or the break up the stone, a technique called burst wave lithotripsy (BWL).
A new technique combining two types of focused ultrasound waves offers a promising approach for treatment of urinary stones located in the ureter, according to a feasibility study in The Journal of Urology®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
When racehorses enter training at about 2 years old, they can develop tiny stress fractures and new bone formations in their legs. This condition, called bucked shin, occurs in about 70% of the animals. In The Journal of the Acoustical Society of America, researchers have developed a method to screen for bucked shin using ultrasound. Axial transmission, in which an ultrasound emitter and receiver are placed on the skin to induce and measure wave velocities, is frequently used to study osteoporosis in humans. The method could detect bucked shin more easily and preserve the health and growth of young horses.

RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven’t been very useful in treating brain tumors and other brain disease. But a team of researchers at Georgia Tech and Emory University has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery of potent medicine to brain tumors.

Rectal cancer, along with colon cancer, is the third-most common type of cancer in the United States, and treatment and surgery greatly affect the quality of life of patients. A multi-disciplinary team at Washington University in St. Louis has developed and tested an innovative imaging technique that is able to differentiate between rectal tissues with residual cancers and those without tumors after chemotherapy and radiation, which could one day help to avoid unnecessary surgeries in some patients who have achieved complete tumor destruction after chemoradiation.

Dr. Mary Beth Cunnane, a radiologist who specializes in the imaging of patients with diseases of the eyes, ears, nose and head and neck, has been appointed Chief of Radiology at Mass Eye and Ear in Boston.
Singing may be the next-generation, noninvasive approach to determining the health of a patient’s thyroid. When a person sings, the vibrations create waves in the tissue near the vocal tract called shear waves. If a tumor is present in the thyroid, the elasticity of its surrounding tissue increases, stiffening, and causing the shear waves to accelerate. Using ultrasound imaging to measure these waves, researchers can determine the elasticity of the thyroid tissue. They demonstrate the technique in Applied Physics Letters.
Researchers have developed a method using ultrasound imaging to score a patient’s lung health, which may help predict if a patient with COVID-19 will worsen. Using 14 points in the lungs, they looked for abnormalities and assigned each spot a score out of 3 based on its severity. Adding up all the points, the researchers found the total lung ultrasound score was higher for those who had a worsening outcome of COVID-19. Umberto Sabatini’s presentation will be a part of the 179th ASA Meeting of the Acoustical Society of America.
Ultrasound can be used to treat cancer when used in combination with molecules that sensitize the system to sound waves. These sonosensitizers generate toxic reactive oxygen species that attack and kill tumor cells. In Applied Physics Review, scientists report a new type of sonosensitizer based on a vanadium-doped titanium dioxide that enhances the amount of damage ultrasound inflicts on tumors. Studies in mice showed that tumor growth was markedly suppressed when compared to a control group.
