Tests and diagnosisBy Mayo Clinic Staff
Ischemic colitis can often be confused with other disorders because their symptoms overlap, especially inflammatory bowel disease (IBD). Based on your signs and symptoms, your doctor may recommend these imaging tests:
Oct. 13, 2015
- Ultrasound and abdominal CT scans, to provide images of your colon that can be helpful in ruling out other disorders, such as IBD.
- Stool analysis, to rule out infection as a cause of your symptoms.
- CT or MRI angiography, to provide detailed images of blood flow in your small intestine and to look for blocked arteries. This test is usually used only if ischemia is suspected in your small bowel as well as in your colon.
- Colonoscopy. This test, which provides detailed images of your colon, can be helpful in diagnosing ischemic colitis. Colonoscopy can also be used to check for cancer, and to see how well a treatment worked.
