Multiparametric MRI with PI-RADSv2 misses ‘considerable number’ of prostate cancer lesions, could still provide value

The combination of multiparametric MRI and the recently revised Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) misses a “considerable number” of clinically significant prostate cancer (PCA) lesions, according to a new study published in the American Journal of Roentgenology. The authors noted, however, that the high positive predictive value (PPV) might make this method useful for imaging active surveillance (AS) patients.
