Ultrasound

Ultrasound uses sound waves to create images of structures inside the body. It does not use X-rays.

What to expect

For many exams, gel is applied to the skin and a handheld transducer is moved over the area being examined. The technique depends on the study ordered.

Before your visit

Preparation depends on the area being examined. Ask the center whether fasting or a full bladder is needed for your appointment.
