ultrasound Ultrasound

A sonogram, or ultrasound, uses sound waves to examine various parts of the body.

A microphone-like instrument, called a transducer, is scanned over the skin on which a gel has been placed.

The gel improves the contact of the transducer to the area being examined. The procedure is painless.


Some sonograms require a full bladder while others require that you not eat or drink after midnight. Please ask the physician or nurse about the exam.

Length of the Procedure

The procedure takes approximately 15 to 60 minutes, depending on the area being examined.

Special Notes

You may be asked to wear a hospital gown for the examination.

Patients should arrive at the registration desk at the front of the hospital approximately 20 minutes prior to their scheduled appointment time.
