Ultrasound is a diagnostic imaging procedure that uses high-frequency sound waves to produce images of structures within the body. These waves are directed into the body through a transducer, a type of probe. The waves reflect off the internal structures and the resounding echoes are captured by the transducer and then processed by a computer. Ultrasound produces real-time or moving images. Ultrasound is often used to evaluate solid or fluid-containing organs in the abdomen and pelvis. Other tissues commonly evaluated by ultrasound include the breasts, thyroid, testicles, and musculoskeletal structures. Ultrasound is also frequently used to detect and measure blood flow in arteries and veins.

How should I prepare for the procedure?

Wear comfortable, loose-fitting clothing for your ultrasound exam. No other preparation is required. If your abdominal vessels are being studied, we will ask you to fast prior to the procedure.

How is the procedure performed?

You will be asked to lie on an examination table that tilts and moves. A clear gel is applied to the area that will be examined. The gel helps to create a smooth “pavement” for scanning and eliminates any air pockets since sound waves are unable to penetrate air. The sonographer sweeps the transducer along the area of interest, reviewing the scans on the monitor and capturing key images. Most ultrasound studies take a minimal amount of time and are painless.

When the examination is complete, you may be asked to dress and wait while the ultrasound images are reviewed and the radiologist has had an opportunity to communicate the results to your physician.
