New technical and clinical developments of sonography and magnetic resonance imaging include improved detection, localization and staging as well as active surveillance of prostate cancer. Multiparametric MRI can best answer these typical clinical questions. However, ultrasound elastography seems to be suitable for the detection of significant prostate cancer as well. The structured reporting system for multiparametric MRI of the prostate according to PI-RADS Version 1 led to improved and reproducible diagnosis of prostate cancer. The new PI-RADS Version 2 aims to minimize the limitations of Version 1 and make PI-RADS standardization more globally acceptable.
Key points: The detection, staging, and active monitoring of prostate cancer are common clinical questions. The best method for answering these questions is multiparametric MRI. Ultrasound elastography also seems to be suitable for the detection of significant prostate cancer. The new PI-RADS Version 2 claims to eliminate the limitations of PI-RADS Version 1 and to allow globally recognized standardized diagnostic reporting.
