The purpose of this study is to assess the benefit of oral contrast administration for identifying the appendix in younger children in the lower weight quartile. Materials and Methods: This retrospective study comprised 100 patients (2\u201310\u00a0years) in lower weight quartile who had intravenous contrast-enhanced CT of the abdomen and pelvis, 37 of which with oral contrast, and 63 without. A pediatric radiologist and a pediatric radiology fellow independently assessed whether the appendix was visualized or not. In case of discrepancy, an additional pediatric radiologist was the \u201ctie-breaker.\u201d Chi-squared test was used to compare the proportion of visualized appendix between the groups (with and without oral contrast). Inter-rater reliability was determined using Cohen\u2019s Kappa coefficient. Results: There was no significant difference in the visualization of the appendix between the group with oral contrast and without ( P = 1). The Cohen Kappa coefficients were .33 (.05, .62) and .91 (.73, 1.00) for the \u201cno oral\u201d and \u201coral\u201d groups, respectively, yielding evidence of a difference ( P = .007). Conclusions: There was no significant difference in the visualization of the appendix using CT with or without oral contrast in low-weight pediatric patients. The inter-rater reliability, however, was significantly higher in the group given oral contrast. Additional studies assessing the value of oral contrast for the sole indication of appendicitis may provide clearer results.<\/jats:p>","DOI":"10.1177\/08465371211064315","type":"journal-article","created":{"date-parts":[[2022,1,6]],"date-time":"2022-01-06T05:56:06Z","timestamp":1641448566000},"page":"568-572","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Is Oral Contrast Beneficial for Visualization of the Appendix in Low-Weight Children?"],"prefix":"10.1177","volume":"73","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6577-8871","authenticated-orcid":false,"given":"Gali","family":"Shapira-Zaltsberg","sequence":"first","affiliation":[{"name":"Department of Medical Imaging, CHEO, ON, Canada"},{"name":"University of Ottawa, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Dien Esquivel","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, CHEO, ON, Canada"},{"name":"University of Ottawa, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas","family":"Mitsakakis","sequence":"additional","affiliation":[{"name":"CHEO Research Institute, ON, Ottawa, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lamia","family":"Hayawi","sequence":"additional","affiliation":[{"name":"CHEO Research Institute, ON, Ottawa, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elka","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, CHEO, ON, Canada"},{"name":"University of Ottawa, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,1,6]]},"reference":[{"key":"bibr1-08465371211064315","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.18.19778"},{"key":"bibr2-08465371211064315","doi-asserted-by":"publisher","DOI":"10.1097\/RUQ.0000000000000118"},{"key":"bibr3-08465371211064315","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.09.3313"},{"key":"bibr4-08465371211064315","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.08.1959"},{"key":"bibr5-08465371211064315","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.09.2336"},{"key":"bibr6-08465371211064315","doi-asserted-by":"publisher","DOI":"10.1007\/s10140-016-1421-2"},{"key":"bibr7-08465371211064315","doi-asserted-by":"publisher","DOI":"10.1007\/s10140-017-1574-7"},{"issue":"8","key":"bibr8-08465371211064315","first-page":"795","volume":"20","author":"Garcia M","year":"2013","journal-title":"AEM"},{"key":"bibr9-08465371211064315","doi-asserted-by":"publisher","DOI":"10.5811\/westjem.2013.5.12950"},{"key":"bibr10-08465371211064315","doi-asserted-by":"publisher","DOI":"10.3148\/71.1.2010.54"},{"key":"bibr11-08465371211064315","doi-asserted-by":"crossref","unstructured":"Albayrak M, Turhan K, Yavuz Y, Kasap zA.\n                      kaphom: An R package for testing the homogeneity of intra-class kappa statistics, Communications in Statistics - Simulation and Computation 2020\n                      ; 49(12): 3283-3298, DOI: 10.1080\/03610918.2018.1538457","DOI":"10.1080\/03610918.2018.1538457"},{"key":"bibr12-08465371211064315","volume-title":"A Language and Environment for Statistical Computing","author":"R Core Team","year":"2020"},{"key":"bibr13-08465371211064315","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.18.19778"}],"container-title":["Canadian Association of Radiologists Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/08465371211064315","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/08465371211064315","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/08465371211064315","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:57:10Z","timestamp":1777384630000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/08465371211064315"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,1,6]]},"references-count":13,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2022,8]]}},"alternative-id":["10.1177\/08465371211064315"],"URL":"https:\/\/doi.org\/10.1177\/08465371211064315","relation":{},"ISSN":["0846-5371","1488-2361"],"issn-type":[{"value":"0846-5371","type":"print"},{"value":"1488-2361","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,1,6]]}}}
