High false-positive rates of prostate cancer diagnosis techniques have resulted in unnecessary biopsies and increased costs of care. This study compared the prostate cancer diagnosis by multiparametric MRI and MRI-ultrasound fusion guided biopsy at our institution, with the ultimate goal of improving MRI diagnosis of prostate cancer. At our institution, multiparametric MRI PI-RADS scores and MRI-ultrasound fusion guided biopsy Gleason scores agreed 46-57% of the time which falls within the ranges in literature.
