Magnetic Resonance Imaging–Ultrasound Fusion Biopsy During Prostate Cancer Active Surveillance

Fusion biopsy using multiparametric magnetic resonance imaging (MRI) and transrectal ultrasound has demonstrated favorable detection rates of high-grade prostate cancer (PCa) among previously undiagnosed men. However, the diagnostic yield among men with active surveillance (AS) remains undefined.To determine the utility of MRI-ultrasound fusion biopsy during AS by reporting rates of PCa upgrading and comparing findings with systematic biopsy.We...
