	Description:		Can you expect a colonoscopy performed via CT scan to be as accurate as a conventional colonoscopy? Physician Judy Yee of the University of California, San Francisco says innovative CT colonographies, or CTCs, are becoming a good alternative. "CT colonography is an imaging test that we would like to use for not only diagnosis of colorectal cancer, but for screening for colorectal cancer. There are many peer-reviewed papers and research that’s been done, including here, comparing the traditional CT colonography method to colonoscopy and have found that they’re pretty much equivalent for the clinically significant polyps. The true 3D, or the virtual holographic version of CT colonography is expected to be as accurate, if not more accurate." Yee is currently conducting larger studies on the procedure, which has proven to have multiple benefits. "So that’s another advantage, actually, of the CTC, is that you don’t need sedation at all."
