Ultrasound is a simple, pain-free diagnostic tool that uses sound waves, not radiation, to produce an image. Also called sonography, ultrasound is a method of “seeing” inside the human body using high-frequency sound waves. As the sound passes through the body, echoes are produced that can be used to identify how far away an object is, how large it is, and how uniform it is. Because ultrasound images are captured in real-time, they can show movement of internal tissues and organs, enabling radiologists to diagnose a variety of illnesses within the body.

Preparing for an Ultrasound

Since preparation requirements vary depending on the area of the body to be examined, your physician will instruct you as to the specific provisions necessary for your particular exam.
