Aim: To reveal the differences in GB polyp size measurements performed by different radiologists on abdominal US. Methods: From June to September 2022, the maximum diameter of 228 GB polyps was measured twice on abdominal US by one of three radiologists (a third-year radiology resident [reader A], a radiologist with 7 years of experience in abdominal US [reader B], and an abdominal radiologist with 8 years of experience in abdominal US [reader C]). Intra-reader agreements for polyp size measurements were assessed by intraclass correlation coefficient (ICC). A Bland\u2013Altman plot was used to visualize the differences between the first and second size measurements in each reader. Results: Reader A, reader B, and reader C evaluated 65, 77, and 86 polyps, respectively. The mean size of measured 228 GB polyps was 5.0 \u00b1 1.9 mm. Except for the case where reader A showed moderate intra-reader agreement (0.726) for polyps with size \u2264 5 mm, all readers showed an overall high intra-reader reliability (reader A, ICC = 0.859; reader B, ICC = 0.947, reader C, ICC = 0.948), indicative of good and excellent intra-reader agreements. The 95% limit of agreement of reader A, B, and C was 1.9 mm of the mean in all three readers. Conclusions: GB polyp size measurement on abdominal US showed good or excellent intra-reader agreements. However, size changes of approximately less than 1.9 mm should be interpreted carefully because these may be within the measurement error.<\/jats:p>","DOI":"10.3390\/tomography10070077","type":"journal-article","created":{"date-parts":[[2024,7,3]],"date-time":"2024-07-03T09:23:59Z","timestamp":1719998639000},"page":"1031-1041","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparison of the Size Measurement of Gallbladder Polyps by Three Different Radiologists in Abdominal Ultrasonography"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4518-8567","authenticated-orcid":false,"given":"Kyu-Chong","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Radiology, Armed Forces Capital Hospital, Seongnam 13574, Republic of Korea"},{"name":"Department of Radiology, Korea University Anam Hospital, 73 Geryeodae-ro, Seongbuk-Gu, Seoul 02841, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Kyem","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Armed Forces Capital Hospital, Seongnam 13574, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7322-2550","authenticated-orcid":false,"given":"Dong-Kyu","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Armed Forces Capital Hospital, Seongnam 13574, Republic of Korea"},{"name":"Department of Radiology, Severance Hospital, Research Institute of Radiological Science, Yonsei University College of Medicine, 50-1 Yonsei-Ro, Seodaemun-Gu, Seoul 03722, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"281","DOI":"10.1080\/00365521.1990.12067104","article-title":"Polyps in the gallbladder.
