However, there is no objective standard for this procedure.Methods: We performed 3T MRI in 10 healthy volunteers and 13 patients with LSS. The ADC values in the spinal canal were evaluated at 46 vertebrae (L4\/5 and L5\/S1 for each participant), and the reduced and conventional fields of view were compared.Results: The ADC values were 2.72\u00b10.12 at L4\/5 in healthy volunteers, 2.76\u00b10.19 at L5\/S1 in healthy volunteers, 1.77\u00b10.58 at L4\/5 in patients with LSS, and 2.35\u00b10.29 at L5\/S1 in patients with LSS. The ADC value at L4\/5 in patients with LSS was significantly lower than that at L5\/S1 in patients with LSS and that at L4\/5 and L5\/S1 in healthy volunteers (&lt;i&gt;p&lt;\/i&gt; &lt;0.05). With an ADC cutoff value of 2.46 to identify LSS, this approach provided an area under the curve of 0.81, sensitivity of 0.92, and specificity of 0.76 (&lt;i&gt;p&lt;\/i&gt; &lt;0.05).Conclusions: Preoperative examination using ADC maps permits visualization and quantification of spinal canal lesions, thus proving the utility of ADC maps in the selection of decompression surgery for LSS.<\/jats:p>","DOI":"10.31616\/asj.2019.0266","type":"journal-article","created":{"date-parts":[[2020,2,13]],"date-time":"2020-02-13T05:26:04Z","timestamp":1581571564000},"page":"312-319","update-policy":"https:\/\/doi.org\/10.31616\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluating
