Ultrasound News and Research

RSS

Ultrasound is a procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.

Integrating Ultrasound with Genetics to Precisely Modify Neurons in the Brain

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.

Research may Offer a New Way to Break Through Cancer's Hypoxia-Induced Defenses

For most of our tissues and cells, a lack of oxygen, or hypoxia, is bad news. Cancer cells, on the other hand, can thrive in these hypoxic conditions, which render tumors less susceptible to anti-cancer treatments, including radiation.
