Virtual colonoscopy for colorectal cancer screening: current status

Abstract

Virtual colonoscopy for colorectal cancer screening: current status - Cancer Imaging Virtual colonoscopy for colorectal cancer screening: current status - Computed tomography colonography (CTC) (also known as `virtual colonoscopy') is a noninvasive method of imaging the colon using helical CT. Although CTC has been shown to be useful for certain clinical indications, it has not yet been endorsed as a colorectal cancer screening test. The purpose of this article is to review the current status of CTC for colorectal cancer screening. CTC is an accurate method to detect colonic polyps and to select patients who would benefit from colonoscopy.
