Figure 1 Mid-sagittal T2-weighted fast spin-echo image of the lumbar spine illustrates the angle measurements which were performed in the study. A-angle was defined by a line parallel to the superior surface of the sacrum and a line perpendicular to the axis of the scan table. B-angle was defined by a line parallel to the superior endplate of L3 vertebra and a line parallel to the superior surface of the sacrum.
