Multi-parameter MRI (Mp-MRI) plays an increasingly important role in the detection, localization and staging of prostate cancer (PCa). To solve the absence of unified criterion of technique and the interpretation of images of Mp-MRI in PCa detection. A recent consensus meeting of PCa experts from ESUR recommended PI-RADS scoring system. True evidence-based guidelines could not be formulated. Our retrospective study proved that PI-RADS scoring was an operable and useful scoring system for interpretation of Mp-MRI used in PCa detection. The diagnostic status of each MR sequence was not at the same level. Only appropriate combined mode was used, the excellent diagnostic efficacy of Mp-MRI can be obtained.
