Outcome measures were four radiographic parameters of the lumbar spine: IVD height (DH); dural sac cross-sectional area (DCSA); and spinal curvature (i.e. lumbar lordosis [LL] and L1-L3-L5 angle [LA]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Major differences (&gt;5%) between standing MRI and BS-MRI methods were observed in DCSA, DH, and LL. Major differences between standing and axial loaded MRIs were observed only in DCSA and LA. Although BS-MRIs demonstrate an image of the lumbar spine curvature (i.e. LA) which is closer to that when standing than axial-loaded MRIs, it is likely to overestimate both narrowing of dural sac and extent of LL.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Using a compression device with a BS to simulate weight-bearing on the lumbar spine is not recommended due to: (i) overestimation of the narrowing of the dural sac and extent of LL; and (ii) underestimation of loss of disc height. Supine axial-loading produced DCSA and DH which were strongly correlated with those detected with standing MRIs. Exceptions were that LL and LA were underestimated.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0284185120951963","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T01:00:55Z","timestamp":1598576455000},"page":"1052-1062","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Lumbosacral spinal compression device with the use of a cushion back support in supine MRI"],"prefix":"10.1177","volume":"62","author":[{"given":"Witaya","family":"Sungkarat","sequence":"first","affiliation":[{"name":"Department of Radiology and Advanced Diagnostic Imaging Center, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiraporn","family":"Laothamatas","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences Technology, HRH Princess Chulabhorn College of Medical Science, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ladawan","family":"Worapruekjaru","sequence":"additional","affiliation":[{"name":"Division of Radiation Oncology, Department of Diagnostic and Therapeutic Radiology, Faculty of Medicine Ramathibodi Hospital, Mahidol University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Boonthida","family":"Hooncharoen","sequence":"additional","affiliation":[{"name":"Advanced Diagnostic Imaging Center (AIMC), Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jarruwat","family":"Charoensuk","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, King Mongkut\u2019s Institute of Technology Ladkrabang, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1308-3389","authenticated-orcid":false,"given":"Khaisang","family":"Chousangsuntorn","sequence":"additional","affiliation":[{"name":"Department of Radiological Technology, Faculty of Medical Technology, Mahidol University, Phutthamonthon, Nakhon Pathom, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,8,27]]},"reference":[{"key":"bibr1-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrnm.2015.06.002"},{"key":"bibr2-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200112010-00016"},{"key":"bibr3-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e31821038f2"},{"key":"bibr4-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0000000000002532"},{"key":"bibr5-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199712150-00021"},{"key":"bibr6-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200112010-00014"},{"key":"bibr7-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181bb8188"},{"key":"bibr8-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/01.brs.0000249513.91050.80"},{"key":"bibr9-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200112010-00015"},{"key":"bibr10-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-009-0919-7"},{"key":"bibr11-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2017.08.251"},{"key":"bibr12-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2015.02.016"},{"key":"bibr13-0284185120951963","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e31815e395f"}],"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0284185120951963","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0284185120951963","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0284185120951963","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T15:26:33Z","timestamp":1777389993000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0284185120951963"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,27]]},"references-count":13,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2021,8]]}},"alternative-id":["10.1177\/0284185120951963"],"URL":"https:\/\/doi.org\/10.1177\/0284185120951963","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8,27]]}}}
