Ultrasound

What is an ultrasound?

An ultrasound study - also called a sonogram - is a medical test that is painless and usually non-invasive. A sonographer performs the test by applying a warm gel to the skin and then placing a transducer above the anatomic structure to be studied. This sends short pulses of ultrasound waves through the body and as the transducer is moved around an image of various organs appears on a television monitor. The high-frequency sound waves and a computer create images of blood vessels, tissues and internal organs.
