CRCs arise within adenomatous polyps,2 and polypectomy is associated with a reduction in CRC incidence and

Context Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC.
Objective To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic individuals at increased risk of CRC using unblinded colonoscopy as the reference standard.
Design, Setting, and Participants This was a multicenter, cross-sectional study.
Individuals at increased risk of CRC due to either family history of advanced neoplasia in first-degree relatives, personal history of colorectal adenomas, or positive results from fecal occult blood tests (FOBTs) were recruited in 11 Italian centers and 1 Belgian center between December 2004 and May 2007. Each participant underwent CT colonography followed by colonoscopy on the same day.
Main Outcome Measures Sensitivity and specificity of CT colonography in detecting individuals
