What is Ultrasound? Definition, Uses, Benefits, and Risks

This is a type of medical imaging test where sound waves are used to produce medical images of different body parts. There’s no radiation involved in ultrasounds. 

Ultrasounds produce an image that is referred to as a sonogram. They’re commonly used throughout pregnancy but they’re also used to diagnose liver problems, heart conditions, joint injuries and certain cancers. Diagnostic ultrasound is usually performed by placing a small device on the area of the body being studied, though some transducers can be used internally, like in the vagina.
