Visual is best: With your family history of colon cancer, you should have visual, not virtual colonoscopy. If a polyp is found, it can be removed and checked for cancer at the same time as your colonoscopy.
Dr. Charles Cattano

Optical vs virtual: While both optical colonoscopy & CT colonography (virtual colonoscopy) examine the lower GI tract, & both require inflation of the colon with air, the optical exam offers several potential advantages in your case where your risk of finding a lesion is high (due to family history & finding occult blood): it is performed sedated; it permits biopsies of inflamed tissue & permits removal of lesions.
Dr. M. Hytham Beck
General Surgery 43 years experience
Colonoscopy better: you have to go through the same preparation and then the virtual colonoscopy required inflating air without sedation which is painful and the accuracy rate have not been established yet and finally if pathology was found you can take care it with colonoscopy not with virtual and last you are sedated while you are having colonoscopy to me that enough good luck
