DWI with different b values (b = 0, 100, 1000 and 1500 s mm\u2212 \u00a02) was obtained. Using the PI-RADS v2, two radiologists independently scored suspicious lesions in each patient and compared DWI of b = 1000 (DWI1000) with 1500 (DWI1500) s mm\u2212 \u00a02 \u00a0.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results:<\/jats:title>\n                  <jats:p>On DWI1000 and DWI1500, the intermethod and interobserver agreements of DWI scores were excellent in all patients (\u03ba \u2265 0.873). In each peripheral zone and transition zone DWI scores, both observers showed excellent intermethod agreement between DWI1000 and DWI1500 (\u03ba \u2265 0.897), and interobserver agreement for DWI1000 and DWI1500 was good to excellent (\u03ba \u2265 0.796). For estimating clinically significant cancer, the area under receiver operating characteristics curves of DWI1000 and DWI1500 were 0.710 and 0.724 for observer 1 (p = 0.11), and 0.649 and 0.656 for
