Computed Tomography Enterography

Computed tomography enterography (CTE) is used to make pictures of the small intestine. The small intestines are part of your digestive system. They lie between the stomach and large intestine. A CTE creates an x-ray picture that is enhanced by a computer. It can provide information about organs, soft tissues, bones, and blood vessels.

  • Call Your Doctor

    Call your doctor if any of the following occurs after the test:

    • Hives
    • Itching
    • Nausea
    • Swollen, itchy eyes
    • Tightness of throat
    • Difficulty breathing

    In case of an emergency, call for medical help right away.

  • What to Expect

  • Reasons for Test

    A CTE may be used to help find the cause of problems in the intestines such as:

    • Swelling
    • Bleeding
    • Tumors
    • Abscesses, which are infected pockets
    • Fistula, which is an abnormal passageway between two areas of the body that normally do not connect
    • Obstruction in intestine


    It may also be used to diagnose or check
    Crohn’s disease.

  • Results

    The CTE images will be sent to a radiologist. Your doctor will receive the results and discuss them with you.

  • Possible Complications

    Complications are rare. If you are planning to have a CTE scan, your doctor will review a list of possible complications.

    Some people have a bad reaction to the contrast dye. The contrast is chemical that improves the details in the pictures. In some people, the contrast can cause allergic reactions or kidney problems.

    A CTE scan does use radiation. You and your doctor will weigh the harms and benefits of this test. A CTE scan may not be advised if you are pregnant.

    Be sure to discuss these risks with your doctor before the test. Let your doctor know about any allergies or unrelated illnesses you may have.
