A. T2WI showed focal hypointense area in anterior TZ of prostate gland (arrow). PI-RADSv2 score on T2WI was 5. B, C. High b-value DWI and ADC map consistently showed focal area of diffusion restriction at corresponding site (arrow). Final PI-RADSv2 score on DWI was 5. Thus, final PI-RADSv2 score was 5 for TZ lesion. D. In surgical specimen, GS 7 PCa was confirmed (dotted area). This is case of GS upgrading, which was suspected by PI-RADSv2. ADC = apparent diffusion coefficient, DWI = diffusion-weighted imaging, GS = Gleason score, PCa = prostate cancer, PI-RADSv2 = Prostate Imaging-Reporting and Data System Version 2, PSA = prostate-specific antigen, TZ = transition zone, T2WI = T2-weighted imaging
