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.

Gamma and neutron imaging safe and effective in simulations

Low risk prostate cancer not always low risk

More and more men who believe they have low-risk prostate cancers are opting for active surveillance, forgoing treatment and monitoring the cancer closely with prostate-specific antigen (PSA) tests, digital rectal exams and ultrasounds at regular intervals to see if their tumors are growing. Nearly 400 men are now enrolled in the UCLA Active Surveillance program, the largest in Southern California.
