Overview

An abdominal ultrasound is done to view structures inside the abdomen. It's the preferred screening method for an abdominal aortic aneurysm, a weakened, bulging spot in the abdominal aorta — the major blood vessel that supplies blood to the body. However, the imaging test may be used to diagnose or rule out many other health conditions.

Doctors recommend an abdominal ultrasound to screen for an abdominal aortic aneurysm in men ages 65 to 75 who are current or former cigarette smokers. If you've never smoked, abdominal aortic aneurysm screening isn't recommended for men (or women), unless your doctor suspects you may have an aneurysm or if you have a family history of an aneurysm.
