Computed tomography (CT) enterography uses special x-ray equipment and an injection of contrast material after the ingestion of liquid to produce detailed images of the small intestine and structures within the abdomen and pelvis. It's often used to identify and locate problems within the bowel, such as inflammation, bleeding, obstructions and Crohn's disease. CT scanning is fast, painless, noninvasive and accurate. CT enterography is better able to visualize the entire thickness of the bowel wall when compared to other small intestine imaging procedures.
