All subjects underwent MRI in a supine position using a 1.5-T scanner (Gyroscan; Philips Medical Systems, Washington, DC, USA). Axial 5 mm slices were acquired using three-dimensional thick T2-weighted spin-echo axial scanning (TR: 3200 ms; TE: 102 ms; FOV: 180 mm; matrix size: 512 × 512) from T12 to L5. The sagittal and axial images were uploaded to the PACS client software (Easy Vision IDS5, version 11.4; Philips, Hamburg, Germany). The axial images were obtained from the intervertebral space parallel to endplates.

Images were analyzed using PACS client software (Easy Vision IDS5, version 11.4; Philips, Hamburg, Germany). Dichotomous variables were tested by χ² test between the control and DSD groups. The independent sample t test was used to compare inter-group parameters. The parameters of DLS group, DK group, and DKS group with DSD were evaluated by analysis of variance. Pearson correlation analysis was used to evaluate the correlation of ACV and DR. Multiple regression model was used to evaluate the influencing factors of ACV and DR. The statistical analysis was performed by SPSS 22.0 (International Business Machines Corporation, Armonk, NY) and statistical significance was defined as P < .05.
