We aimed to test a simpler imaging finding of SMA syndrome. This cross\u2010sectional case\u2010reference study examined whether right movement of the SMA on unenhanced computed tomography (CT) is useful for the diagnosis of SMA syndrome. We reviewed hospital records of patients admitted in 2008\u20132018. Each case was matched to one non\u2010case patient of the same age and sex. On unenhanced CT scans, we identified the shortest distance between the parallel line that passes through the center of the aorta to the line that bisects the spine and SMA. A negative number of the distance means that the SMA is on the left side of the above\u2010described parallel line. There was a total of 14 cases and 14 non\u2010cases (men, 57.1%) with mean age 78.7\u2009years. Mean body mass index of cases and non\u2010cases were 19.2 and 22.2\u00a0kg\/m<jats:sup>2<\/jats:sup>, respectively. The more prevalent side of the SMA was the right side. The mean shortest distance was 10.5\u2009mm in cases and 0.7\u2009mm in non\u2010cases (<jats:italic>p<\/jats:italic> for independent <jats:italic>t<\/jats:italic> test\u00a0=\u00a00.043). For comparing the observations in SMA cases at several time points, the mean shortest distance at pre\u2010onset was \u22122.7\u2009mm, with a significant difference from that at onset (<jats:italic>p<\/jats:italic> for paired <jats:italic>t<\/jats:italic> test\u00a0=\u00a00.030). In conclusion, right movement of the SMA diagnosed by unenhanced CT is associated with SMA syndrome.<\/jats:p>","DOI":"10.1002\/ca.23885","type":"journal-article","created":{"date-parts":[[2022,4,13]],"date-time":"2022-04-13T16:08:50Z","timestamp":1649866130000},"page":"891-898","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Movement of the superior mesenteric artery in patients with superior mesenteric artery syndrome: A case\u2010reference study"],"prefix":"10.1002","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7943-4930","authenticated-orcid":false,"given":"Jun","family":"Miyata","sequence":"first","affiliation":[{"name":"Department of Island and Community Medicine Nagasaki University Graduate School of Biomedical Sciences  Nagasaki Japan"},{"name":"Public Health, Department of Social Medicine Osaka University Graduate School of Medicine  Suita Osaka Japan"},{"name":"Department of Family Medicine, Medical Center for the Entire Family Keiju Medical Center  Nanao Ishikawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ehab Salah","family":"Eshak","sequence":"additional","affiliation":[{"name":"Public Health, Department of Social Medicine Osaka University Graduate School of Medicine  Suita Osaka Japan"},{"name":"Department of Public Health and Community Medicine Minia University  Minia Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuya","family":"Yoshioka","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, Medical Center for the Entire Family Keiju Medical Center  Nanao Ishikawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyasu","family":"Iso","sequence":"additional","affiliation":[{"name":"Public Health, Department of Social Medicine Osaka University Graduate School of Medicine  Suita Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,4,22]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198811000-00013"},{"key":"e_1_2_6_3_1","first-page":"545","article-title":"Surgical anatomy of the superior mesenteric artery","volume":"31","author":"Derrick J.
