Virtual colonoscopy, now ten years old, has made substantial progress in the detection of adenomas and colorectal cancer. Recent studies report comparable sensitivities and specificities to conventional colonoscopy for polyps 10 mm or larger on a per polyp basis. CTC is currently approved by Medicare as a diagnostic study in patients with positive symptoms and after failed colonoscopy. Work continues to approve CTC as a colorectal cancer screening exam. Many experts believe CTC is also ready to be adopted into the colorectal screening algorithm. [Pg.22]

Although only three paired CT examinations were assumed for screening by virtual CT colonoscopy, organ doses are relatively high for the intestinal sites. Consequently, the estimated LAR is high compared to the Hfetime basehne risk of colorectal cancer. [Pg.93]
