An Abdominal Aorta Duplex uses sound waves to check the circulation to the abdomen. The test is noninvasive, which means no needles, catheters, or dyes are used. Ultrasound is used to create a picture of the shape of tissues and organs inside your body. The walls of blood vessels, including any deposits or narrowing, can also be seen.
Gel is placed on the skin over the area to be studied. An instrument, called a transducer, is placed on your skin. Sound waves are transmitted from the transducer. The sound waves reflect off the tissues and organs to create a picture that can be seen on a screen. Blood flow through the blood vessels can be heard as the test is being completed.
How to prepare: Nothing to eat or drink 8 hours prior to the test. You may take small sips of water if medicine is necessary. Do NOT chew gum or smoke on the day of the test. When you eat, drink or even chew gum you swallow air into the stomach and bowel, which can reduce visibility of the arteries. Wear comfortable, two-piece clothing.
