Digitel - another naysayerVirtual colonoscopy is used for screening people who have no symptoms. There is very little effectiveness to support it at present and colonoscopy is the gold standard right now. Even if virtual colonoscopy does enter the mainstream market, the polyps still need to be removed. Who do you think will do that? Don't forget that CRH main brand is related to their O'Regan system. Again as I said to truthseeker, if you hold a position then say so. Then discussing about CRH would hold a lot of credibility if you are providing some constructive arguments.
