How can a virtual colonoscopy diagnose diseases of the digestive system?

ANSWER

A computer can take CT images of the colon and make a 3-dimensional model of your colon -- called a virtual colonoscopy. The inside of this model can be inspected, obviously without causing any pain to you, while searching for problems. But if a problem is found, a scoping test -- either sigmoidoscopy or colonoscopy -- will be needed to get a tissue sample.
