The FSR obtained using 3D-MRI, described as the ratio of stenosis length, characterized by perineural fat obliteration, to the length of the entire foramen, could indicate the stenosis severity; however, this method is time-consuming and expensive. The FSR also can be calculated using conventional MRI.Methods: We investigated 154 foramina at L5\u2013S1 in 77 patients. All the patients had degenerative lumbar disorders and had undergone both conventional MRI and 3D-MRI during the same visit. Differences between the FSRs calculated from conventional and 3D-MRI reconstructions and any correlations with the plain radiography findings were assessed.Results: In foramina that had a FSR of &lt;50% on conventional MRI, the difference between the FSR obtained using conventional MRI and 3D-MRI was 5.1%, with a correlation coefficient of 0.777. For foramina with a FSR \u226550% on conventional MRI, the difference was 20.2%, with a correlation coefficient of 0.54. FSR obtained using 3D-MRI was significantly greater in patients who required surgery than in those who were successfully treated with conservative methods (88% and 42%, respectively). Segments with spondylolisthesis or lateral wedging showed higher FSRs than those without these conditions on both types of MRI.Conclusions: FSRs &lt;50% obtained using conventional MRI were sufficiently reliable; however, the results were inaccurate for FSRs \u226550%. Patients with high FSRs on 3D-MRI were more likely to require surgical treatment. Therefore, 3D-MRI is recommended in patients with suspected stenosis detected using conventional MRI or plain radiographs.<\/jats:p>","DOI":"10.31616\/asj.2020.0133","type":"journal-article","created":{"date-parts":[[2020,10,16]],"date-time":"2020-10-16T07:29:21Z","timestamp":1602833361000},"page":"472-480","update-policy":"http:\/\/dx.doi.org\/10.31616\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Can
