Voxel level statistical analysis of RSI-MRI cellularity index versus benign or malignant tissue in histopathological section (GGs 3–5). A linear mixed-effects model with a random effect of subject was implemented to compare difference in detection among benign tissue versus low-grade prostate cancer (primary Gleason 3) versus high-grade prostate cancer (primary Gleason ≥4)
