Box plots of A ADC values and B (choline + spermine + creatine)/citrate ((Cho + Spm + Cr)/Cit) values of low-risk, intermediate-risk and high-risk transition zone prostate cancer tissues. The correlations with low-risk, intermediate-risk and high-risk prostate cancer tissues were evaluated with Spearman correlation coefficients. MR parameters of ROIs with normal transition zone tissue are shown for comparison (shaded)
