Open Access Colonoscopy

Why would I opt for the regular colonoscopy if I could get a virtual one? 
First, most people report that the worst part of the colonoscopy is the bowel-cleansing prep, and you still have to do that with a virtual test. The virtual test is also somewhat invasive—your colon is filled with air via a short tube in the rectum. If significant polyps are spotted, you will have to have a regular colonoscopy to remove them, and doing so immediately may not be possible—which would mean a repeat of the bowel prep on another day. Finally, virtual colonoscopy isn't usually covered by insurance, though that may change with this endorsement.
