CT colonography of a Medicare-aged population: outcomes observed in an analysis of more than 1400 patients.
OBJECTIVE
We evaluated outcomes of patients 65 years old and older who underwent CT colonography (CTC) between 2004 and 2009.


CONCLUSIONS
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 CTC a viable option for Medicare-aged patients.
