One-third of CRCs arise via the sessile serrated pathway. Evidence supports using CTC to detect adenomas and CRC; however, its accuracy for sessile serrated lesions (SSLs) remains uncertain. This study aimed to determine the accuracy of CTC in detecting SSLs compared with colonoscopy.\nmethod: Electronic records identified all colonoscopy procedures where a histologically validated SSL was excised over a 11-month period. In those patients who had a CTC within 1 year prior to colonoscopy, the presence, size and location of SSLs were compared to determine the accuracy of CTC in SSL identification.\nresults: A total of 4,346 procedures were performed (2,548 people, 2,082 [47.9%] male, mean age 59.6). A total of 2,204 SSLs were removed, representing 24% of all polypectomies. SSLs were predominantly located in the right colon (65.1%) and were typically (85%) &lt;10mm in size. A total of 110 SSLs were obtained from 39 procedures with a prior CTC. Of these procedures, 12 (30.8%) had lesions identified on CTC; however, CTC only accurately identified 14.5% of the total SSLs. Five of 16 (32%) SSLs \u226510mm were correctly identified compared with 11 of 94 (11%) SSLs 1\u20139mm, (odds ratio 3.42, p=0.0495).\nconclusion: This study demonstrated that CTC has poor efficacy in detecting SSLs, irrespective of polyp size and location. Based on these findings, CTC as a substitute for colonoscopy is not advisable in patients at risk of SSLs.<\/jats:p>","DOI":"10.26635\/6965.7109","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T23:55:56Z","timestamp":1765238156000},"page":"28-35","source":"Crossref","is-referenced-by-count":0,"title":["Computed tomography colonography performs poorly in detection of sessile serrated lesions"],"prefix":"10.26635","volume":"138","author":[{"given":"Shiristi","family":"Kumar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"McCombie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon","family":"Richards","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamara","family":"Glyn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emma","family":"Bone","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tim","family":"Eglinton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"11177","published-online":{"date-parts":[[2025,12,12]]},"container-title":["New Zealand Medical Journal"],"original-title":[],"deposited":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T23:55:56Z","timestamp":1765238156000},"score":1,"resource":{"primary":{"URL":"https:\/\/nzmj.org.nz\/journal\/vol-138-no-1627\/computed-tomography-colonography-performs-poorly-in-detection-of-sessile-serrated-lesions"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,12]]},"references-count":0,"journal-issue":{"issue":"1627","published-online":{"date-parts":[[2025,12,12]]}},"URL":"https:\/\/doi.org\/10.26635\/6965.7109","relation":{},"ISSN":["1175-8716"],"issn-type":[{"value":"1175-8716","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,12]]}}}
