Tests and diagnosis

By Mayo Clinic Staff

Based on your signs and symptoms, your doctor may recommend these imaging tests:

  • CT or MR angiography, to provide detailed images of blood flow in your small intestine and to look for blocked arteries. Sometimes, the doctor can treat the blocked arteries during the angiogram.
  • Arteriography, to provide X-ray images of blood vessels.

Other procedures include:

  • Endoscopy, to image the upper part of your small intestine. Endoscopy can help your doctor rule out other conditions as the cause of your digestive problems.
  • Colonoscopy, to image the large intestine.
  • Exploratory surgery, to locate and remove damaged tissue. Exploratory surgery allows for diagnosis and treatment during one procedure.
