Core Tip
Core tip: In this study, novice readers and experienced radiologists had similar accuracy rates for the detection of colonic neoplasia utilizing computed tomography colonography (CTC) as a screening tool. The optimal number of scans required to achieve satisfactory performance in CTC interpretation was not identified suggesting that larger scale studies are required to identify the training requirements necessary for adequate CTC interpretation. Patient preferences for CTC and colonoscopy were assessed by means of a self completion survey and patients were found to prefer colonoscopy to CTC as a screening tool, likely because of the use of conscious sedation.
