    What is an Abdominal Ultrasound?

    An abdominal ultrasound (sonogram) uses reflected sound waves to produce images (pictures) of the abdomen (stomach) and internal organs. A sonographer performs an ultrasound examination. A transducer (a small, hand-held device that looks like a microphone) is placed over the area to be examined and records images electronically. Ultrasound images of the abdomen show organs like the gallbladder, spleen, pancreas, kidneys, liver and bile ducts as well as blood flow to the organs. Ultrasound does not use x-ray or other types of radiation.

    What Will I Experience During an Abdominal Ultrasound?

    • Ultrasound imaging of the abdomen is painless, fast, and easy.

    • You change into a gown for this test. The examination takes about 30 minutes.

    • You are positioned on your back on a firm table in the Radiology department. Pillows are provided for your comfort.

    • First, the sonographer applies a warm, clear gel on your abdomen to help the transducer make direct contact with the skin.

    • Next, the sonographer places the transducer firmly against your skin, and moves it back and forth to see the images of your abdomen on the screen.

    • There may be mild discomfort from pressure as the sonographer moves the transducer over your abdomen, especially if you are having abdominal pain.

    • After the exam, the sonographer reviews the ultrasound images with a radiologist.
