Due to higher participation rates, CT colonography screening for colorectal cancer is more cost-effective than colonoscopy screening, according to a study in Radiology. Here are four things to know. 1 ...

Initial CTC screening performed as well as universal colonoscopy in the detection of advanced neoplasia — and minimized the risk for perforation. In earlier studies, the accuracy of computed ...
