The goal of this study is to evaluate the diagnostic value of different ADC values (incuding ADCmin, ADCmean, ADCratio and ADCrange) of bpMRI in patients with PI-RADS 3-5. The main aim is to evaluate whether different ADC values improve the diagnosis of clinically significant prostate cancer (Gleasonscore≥3+4, ISUP grade ≥2) and any-grade prostate cancer (Gleasonscore≥3+3, ISUP grade ≥1).
