The pathologies were confirmed by in-bore MR-guided biopsy. The postprocessing and measurements were processed using the software tool Matlab R2015b for the IVIM-kurtosis model and MEM.

Mean values of <jats:italic>D<\/jats:italic>, <jats:italic>D<\/jats:italic>*, <jats:italic>f<\/jats:italic>, <jats:italic>K<\/jats:italic>, ADC, and their histogram parameters were acquired. The values of these parameters in PCa and benign prostatic hyperplasia (BPH)\/prostatitis were compared. Receiver operating characteristic (ROC) curves were used to investigate the diagnostic efficiency.

For MEM, ADC (mean, 10th, 25th, 50th, 75th, 90th) was significantly lower in PCa than in BPH\/prostatitis. The area under the ROC curve (AUC) of the IVIM-kurtosis model was higher than MEM, without significant differences (<jats:italic>z<\/jats:italic> = 1.761, <jats:italic>P<\/jats:italic> = 0.0783). <jats:italic>D<\/jats:italic>\u00a0(mean, 50th, 75th, 90th), <jats:italic>D<\/jats:italic>* (mean, 10th, 25th, 50th, 75th), and <jats:italic>f<\/jats:italic> (skewness, kurtosis) correlated negatively with GS, while <jats:italic>D<\/jats:italic> (kurtosis), <jats:italic>D<\/jats:italic>* (skewness, kurtosis), <jats:italic>f<\/jats:italic> (mean, 75th, 90th), and <jats:italic>K<\/jats:italic> (mean, 75th, 90th) correlated positively with GS.
