Diagnosis

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:

• Abdominal CT scans, to provide images of your colon that can be helpful in ruling out other disorders, such as IBD.
• 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.
• Stool analysis, to rule out infection as a cause of your symptoms.
