Coloscopie virtuelle CT

I recently has a colonoscopy what it was incomplete due to scar tissue. Thank goodness my biopsy was negative so no cancer which was the worries I had. The doctor said since he could not complete it I would have to go do a CT Virtual Colonoscopy. Has anyone had one?

It sounds like something being inserted into your system, but didnt they say they could not find cancer. So it should mean you are in the clear. Cancers are easy to pick up.
