The radiologist and endoscopists were blinded to each other's findings. Patients underwent a polyethylene glycol bowel preparation, and were scanned in prone and supine positions using a single-detector helical CT scanner and commercially available software for image analysis. Findings were validated (matched) in an unblinded comparison with video-recordings of the CCs and re-CCs in cases of doubt.<\/jats:p>\n                  <jats:p>Results: For patients with polyps \u2a7e5\u2005mm and \u2a7e10\u2005mm, the sensitivity was 69% (95% CI 58\u201380%) and 81% (68\u201394%), and the specificity was 91% (84\u201398%) and 98% (93\u2013100%), respectively. For detection of polyps \u2a7e5\u2005mm and \u2a7e10\u2005mm, the sensitivity was 66% (57\u201375%) and 77% (65\u201389%). A flat, elevated low-grade carcinoma was missed by CTC. One cancer relapse was missed by CC, and a cecal cancer was missed by an incomplete CC and follow-up double-contrast barium enema.<\/jats:p>\n                  <jats:p>Conclusion: CC was superior to CTC and should remain first choice for the diagnosis of colorectal polyps. However, for diagnosis of lesions \u2a7e10\u2005mm, CTC and CC should be considered as complementary methods.<\/jats:p>","DOI":"10.1080\/02841850701422096","type":"journal-article","created":{"date-parts":[[2009,12,9]],"date-time":"2009-12-09T07:31:39Z","timestamp":1260343899000},"page":"831-837","source":"Crossref","is-referenced-by-count":8,"title":["Diagnostic performance of computed tomography colonography and colonoscopy: a prospective and validated analysis of 231 paired examinations"],"prefix":"10.1177","volume":"48","author":[{"given":"R.
