Computed Tomography (CT or CAT) Scan of the Abdomen

General Information:

  • Description: A CT scan involves taking X-ray pictures of the body and using computers to combine these pictures into a high-resolution image, making small abnormalities detectable. A radiology technician performs the test at an x-ray facility. The results are interpreted by a radiologist. A CT scan takes about an hour to complete. 
  • Discomfort: Minimal. An intravenous line has to be placed. The x-ray table can be uncomfortable to some people, the contrast dye can cause a hot flush and some people may experience anxiety during the test. 
  • Results: Usually within 1-2 days. Results can be available within 1 hour in emergency situations.
  • Risks of Procedure: Adverse reactions to contrast dye, risks associated with radiation during pregnancy

Preparation:

  • You remove all clothing and wear a hospital gown. 

Procedure:

  • About one hour prior to the test you may be asked to drink a solution of barium to provide an outline of the digestive tract. Contrast dye may be injected into your vein to highlight blood vessels.  The CT table, with the patient lying flat, is slowly moved through the center of the CT scanner.
