CT enterography is a special type of computed tomography (CT) imaging performed with contrast material to produce images of the small intestine.
SMIL performs CT enterography to identify and locate inflammation, bleeding sources, tumors, abscesses and fistulas, and bowel obstructions.
CT enterography is also used to diagnose, evaluate and guide the treatment of patients with Crohn's Disease, including monitoring the effectiveness of treatment.
Prior to the procedure, you will be asked to drink several glasses of a liquid solution that contains a contrast material. The total amount of fluid you will need to drink is approximately 1 to 1.5 liters. You should inform your doctor if you think you will not be able to drink this amount of contrast. You will drink the contrast material over a period of approximately one hour in order to fill the long small intestine. The fluid expands the small bowel so that abnormalities can be seen with better clarity.
The SMIL technologist begins by positioning you on the CT examination table, usually lying flat on your back or less commonly, on your side or on your stomach.
Next, the table will move quickly through the scanner to determine the correct starting position for the scans. Then, the table will move slowly through the machine as the actual CT scanning is performed.
Learn how to prepare for the scan in the CT enterography preparations section.
