Ultrasound is an imaging technique that uses sound waves to produce images of the organs, vessels, and the tissues in the body. There is no radiation, which is why ultrasound is used during pregnancy to access the fetus. Ultrasound has many other applications. It can be used to detect cysts or gallstones, examine the breast, prostate, liver, kidneys, pancreas, spleen, colon, and bladder. Ultrasound can also be used to guide needle placements for biopsies and to drain cysts or fluid collection in the body.

The technologist brings you to the exam room where the procedure is explained to you. You are instructed to lie on the ultrasound table for the exam. The technologist applies a special gel to your skin and/or to the transducer. During the procedure, you feel light pressure from the transducer being moved over your skin. Most exams range from 30 minutes to one hour.

Your physician provides you with detailed instruction describing how to prepare for the procedure. If you take any medications, ask your physician if you should take them before your procedure. On the day of the exam wear loose, comfortable clothing.

A radiologist, a physician specially trained to diagnose conditions and diseases by obtaining and interpreting medical images, interprets the results of your exam. The radiologist sends an interpretation of your results and a signed report to your primary care physician. Your doctor discusses these results with you and explains, what they mean in relation to your health.
