The outcome measures included seven radiologic parameters of the lumbar spine: measures of the intervertebral disc (i.e. cross-sectional area [DA], disc height [DH], and anteroposterior distance [DAP]), dural sac (cross-sectional area [DCSA]), spinal curvature (i.e. lumbar lordosis [LL] and L1-L3-L5 angle [LA]), and total lumbar spine height (LH).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>For agreement between the two methods, intraclass correlation coefficient (ICC)\u2009\u2265\u20090.8 was found for all seven radiologic parameters. Supine axial-loaded MRI underestimated LL but remained correlated (ICC\u2009=\u20090.83) with standing MRI. Minor differences between the two methods (\u22645.0%) were observed in DA, DCSA, DAP, LA, and LH, while a major difference was observed in LL (8.1%).<\/jats:p>\n                  <\/jats:sec>\n
