MRI images of the lumbar spine. (A) T2-weighted images, apparent diffusion coefficient (ADC) pseudocolor images, and fractional anisotropy (FA) pseudocolor images are listed from top to bottom, respectively. (B) The bar graph shows the Pfirrmann classification at 56 days. (C-D)The bar graphs show the ADC and FA values at 56 days. Data are expressed as mean ± SD. **P < 0.01 indicates significant differences compared to the sham compressed group, and ##P < 0.01 compared to the model group
