Ultrasound
Ultrasound (also called sonography or ultrasonography) is a noninvasive imaging test. Ultrasound uses high-frequency sound waves to create real-time pictures or video of internal organs or other soft tissues, such as blood vessels. Ultrasound enables healthcare providers to see details of soft tissues inside your body without making any incisions. Unlike X-rays, ultrasound doesn’t use any radiation.
Although most people associate ultrasound with pregnancy, healthcare providers use ultrasound for many different situations and to look at several different parts of the inside of your body.
