Tests and diagnosisBy 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.
