What is CT Enterography?
CT Enterography is a non-invasive imaging technique used to obtain detailed images of the small intestine. This procedure uses a contrast dye and a specialized CT scan to detect inflammatory conditions, tumors, strictures, and bleeding in the intestines. It is particularly useful in diagnosing Crohn’s disease, celiac disease, and small bowel tumors.

When is CT Enterography Recommended?

  • Chronic abdominal pain or diarrhea

  • Suspected Crohn’s disease or inflammatory bowel disease (IBD)

  • Small bowel tumors or polyps

  • Unexplained gastrointestinal bleeding

  • Bowel obstructions or strictures

  • Malabsorption disorders like celiac disease

How is CT Enterography Performed?

  1. Preparation:

    • The patient must fast for 4–6 hours before the scan.

    • A special oral contrast solution (to expand and highlight the intestines) is given 45–60 minutes before the procedure.

    • A contrast dye (iodine-based) is injected into a vein to enhance blood vessel and tissue visibility.

  2. CT Scan & Image Capture:

    • The patient lies on a CT scan table, which moves through the scanner.

    • Multiple high-resolution images are taken as the contrast moves through the intestines.

    • The scan captures detailed cross-sectional images of the entire small intestine.

  3. Completion & Recovery:

    • The scan typically takes 30–45 minutes.

    • Patients can resume normal activities immediately, unless advised otherwise.

    • Drinking plenty of water helps flush out the contrast dye and oral solution.

Benefits of CT Enterography

  • High-resolution imaging of the small intestine

  • Accurate diagnosis of Crohn’s disease, tumors, and obstructions

  • Non-invasive and faster than traditional small bowel studies

  • Detects early signs of inflammation and bleeding
