Histogram parameters of the tumor from the SEM [distributed diffusion coefficient (DDC) and \u03b1] and the monoexponential model [MEM; apparent diffusion coefficient (ADC)] were evaluated. The associations between parameters and Gleason score or Prostate Imaging Reporting and Data System v. 2 were evaluated. The area under the receiver operating characteristics curve was calculated to evaluate diagnostic performance of parameters in predicting CSC.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results:<\/jats:title>\n                  <jats:p>The values of histogram parameters of DDC and ADC were significantly lower in patients with CSC than in patients without CSC (p &amp;lt; 0.05), except for skewness and kurtosis. The value of the 25th percentile of \u03b1 was significantly lower in patients with CSC than in patients without CSC (p = 0.014). Histogram parameters of ADC and DDC had significant weak to moderate negative associations with Gleason score or Prostate Imaging Reporting and Data System v. 2 (p &amp;lt; 0.001), except for skewness and kurtosis. For predicting CSC, the area under the curves of mean ADC (0.856), 50th percentile DDC (0.852), and 25th percentile \u03b1 (0.707) yielded the highest values compared to other histogram parameters from each group.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>Histogram analysis of the SEM on diffusion-weighted imaging may be a useful quantitative tool for evaluating CSC.
