At present: there is no suitable replacement for a screening or diagnostic colonoscopy. There is a CT procedure known of as a "virtual colonoscopy," but it lacks the diagnostic sensitivity to truly replace a colonoscopy. If your doctor is doing the colonoscopy to diagnose a particular condition, it is particularly important, as they may need to do a biopsy, which can't be done by CT. Hope this helps!
