CT colonography: Coming of age

OBJECTIVE. The purpose of this article is to highlight key issues in CT colonography (CTC) for radiologists so they can represent the technology accurately to referring physicians and provide a perspective that will hopefully augment best care for their patients. CONCLUSION. With publication of the National CT Colonography Trial and the endorsement of CTC for screening by a multisociety task force that included the American Cancer Society, American College of Radiology, and U.S. Multisociety Task Force on Colorectal Cancer, the clinical validation of CTC has been completed, and CTC is now ready for widespread clinical application. Radiologists must be skilled in CTC and knowledgeable about colorectal cancer screening issues.
