  1. DWI Diffusion weighted imaging, ADC Apparent diffusion coefficient
  2. Sagittal gradient-echo diffusion weighted echo-planar imaging (EPI) with fat saturation was performed on 1.5 T Magnetom Avanto scanners with B19 software (Siemens Healthineers, Erlangen, Germany). The system software generated ADC maps based on the three tabled b values and an average measure for the three orthogonal directions of diffusion sensitization. The integrated spine array coil was used, and no surface coils
