What is virtual colonoscopy?

ANSWER

This test helps your doctor see inside your rectum and colon (also called your large intestine). You might hear her call it CT colonography, or computed tomography, a kind of test that takes pictures of your insides. It’s most often used to look for small growths called polyps and to check for colon or rectal (colorectal) cancer.
