Recognizing that CT colonography will play a role in screening for colorectal cancer (CRC), and the critical need to increase overall CRC screening rates, the American Gastroenterological Association (AGA) Institute issued minimum standards for gastroenterologist performance of the test. To ensure competence, a minimum of 75 endoscopically confirmed cases should be interpreted by the physician.
Despite the fact that CT colonography has not yet been endorsed as a primary screening test in asymptomatic, normal risk adults, many patients have shown interest in this test. The indications for CT colonography are controversial, with many payers recommending that this test only be indicated for patients who have had a failed optical colonoscopy or who have a mass obstructing the colon where examination of the entire colon is required prior to surgical resection. Nonetheless, CT colonography may be considered for patients unwilling to undergo other colorectal screening tests, note the authors of the standards paper, which is published in Gastroenterology, the official journal of the AGA Institute.
