CT Colonography of a Medicare-Aged Population: Outcomes Observed in an Analysis of More Than 1400 Patients
American Journal of Roentgenology, 06/26/2012
Cash BD et al. – The frequency of referral to colonoscopy based on a polyp size threshold of 6 mm was 14.5%. Colorectal neoplasia was found in 9.3% of patients, with advanced neoplasia in 3.3%. Potentially important extracolonic findings were observed in 2.9% of patients. The low rates of referral to colonoscopy, prevalence of advanced neoplasia, and prevalence of extracolonic findings make CT colonography (CTC) a viable option for Medicare–aged patients.
