Patients and Methods: 21 children who had WBMRI at both 1.5 and 3 T scanners within a relatively short interval (3-13 months; average-8.6 months) were included. The images were objectively compared with scores from 4 to 1 for five parameters including severity of artifacts; visibility of liver, vertebral column, and marrow in legs; and overall image quality. Inter-observer agreement was calculated using Kendall's coefficient of Concordance (W) and scores were compared using Signed Rank test. Results: There was substantial inter-observer agreement for all five categories at both field strengths. The difference between averages of mean scores of all five parameters for two field strengths was statistically significant (P &lt; 0.05), indicating less artifact, better fixed structure visibility, and overall image quality at 1.5 T as compared to 3 T. However, scores at 3 T were also rated within a good range (around 3) indicating its feasibility for WBMRI in children. Conclusion: WBMRI at 1.5 T has significantly better image quality, fixed structure visibility, and fewer artifacts, as compared to WBMRI at 3 T in children. This difference is unlikely to significantly affect detection of pathology on 3 T WBMRI as the image quality score at 3 T was also within good range.\n<\/jats:p>","DOI":"10.4103\/0971-3026.169448","type":"journal-article","created":{"date-parts":[[2015,11,12]],"date-time":"2015-11-12T07:20:23Z","timestamp":1447312823000},"page":"353-358","source":"Crossref","is-referenced-by-count":15,"title":["Pediatric whole-body magnetic resonance imaging: Intra-individual comparison of technical quality, artifacts, and fixed structure visibility at 1.5 and 3 T"],"prefix":"10.1055","volume":"25","author":[{"given":"Shyam","family":"Mohan","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Imaging, The Hospital for Sick Children and Medical Imaging Department, University of Toronto, Toronto, Ontario, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahim","family":"Moineddin","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, University of Toronto, Toronto, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Govind B","family":"Chavhan","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Imaging, The Hospital for Sick Children and Medical Imaging Department, University of Toronto, Toronto, Ontario, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,7,30]]},"container-title":["Indian Journal of Radiology and Imaging"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.4103\/0971-3026.169448.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,8,2]],"date-time":"2021-08-02T05:53:51Z","timestamp":1627883631000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.4103\/0971-3026.169448"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,10]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2021,7,30]]},"published-print":{"date-parts":[[2015,10]]}},"URL":"https:\/\/doi.org\/10.4103\/0971-3026.169448","archive":["Portico","CLOCKSS"],"relation":{},"ISSN":["0971-3026","1998-3808"],"issn-type":[{"value":"0971-3026","type":"print"},{"value":"1998-3808","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,10]]}}}
