 We choose to study men undergoing first-time biopsy, since the great challenge with prostate biopsy today is to establish a correct diagnosis initially. The study sample is kept uniform by excluding men with prior negative biopsies and men enrolled in the Active Surveillance program. Men without a targetable lesion and men with a PI-RADS 2 lesion currently undergo a mapping biopsy under an existing IRB approval; data collection on these men would continue in parallel, but would not be part of this targeting study
