What are the tests for diverticulosis and diverticulitis?

Diverticulosis: Because diverticula by themselves usually do not cause problems, most people learn they have diverticulosis during routine screening examinations for colorectal cancer or during tests that check for other intestinal problems. Diverticulitis, on the other hand, is usually diagnosed during an acute attack.

CT & scope.: A CT scan and a colonoscopy will generally identify diverticuli. A colonoscopy should NOT be done if acute diverticulitis is suspected, just a CT.
