Why it's done
By Mayo Clinic staffVirtual colonoscopy is used to screen for colon cancer.
Because virtual colonoscopy involves the entire abdominal and pelvic area, problems unrelated to colon cancer — such as an aortic aneurysm in the abdominal area or a tumor in the kidney, liver, pancreas or spleen — could potentially be found as well.
