An ultrasound uses sound waves to capture images from inside your body. It’s a noninvasive screening procedure that can evaluate and diagnose a number of conditions, specifically those involving tissues, organs, and blood vessels. It uses no radiation, so it’s quite safe.
An ultrasound doesn’t cause pain. During the test, the technician applies a gel to the area to be examined to facilitate smooth movement of the ultrasound wand. This wand, called a transducer, is then applied to your skin to send sound waves deep into your body.
