[MR imaging of the prostate].

CLINICAL ISSUE: Prostate cancer is the most common form of cancer in men in Germany; however, there is a distinct difference between incidence and mortality. STANDARD TREATMENT: The detection of prostate cancer is based on clinical and laboratory testing using serum prostate-specific antigen (PSA) levels and transrectal ultrasound with randomized biopsy. DIAGNOSTIC WORK-UP: Multiparametric MR imaging of the prostate can provide valuable diagnostic information for detection of prostate cancer, especially after negative results of a biopsy prior to repeat biopsy. PERFORMANCE: In addition the use of MR ultrasound fusion-guided biopsy has gained in diagnostic importance and has increased the prostate cancer detection rate. ACHIEVEMENTS AND PRACTICAL RECOMMENDATIONS: The prostate imaging reporting and data system (PI-RADS) classification has standardized the reporting of prostate MRI which has positively influenced the acceptance by urologists.
