Magnetic Resonance Imaging-Targeted Biopsy Of The Prostate

Before a transrectal ultrasound-guided biopsy, a magnetic resonance imaging (MRI) scan can be used to pinpoint the location of suspicious lesions in the prostate. Use of MRI permits a targeted biopsy (as opposed to a blind biopsy, which is the current standard of care). The use of an MRI-guided prostate biopsy serves 2 functions: (1) to identify areas in the prostate that could harbor a high-grade tumor; and (2) to divert attention from any clinically insignificant cancers not needing treatment. In accomplishing the secondary function, patients are placed into 1 of 2 categories: those only needing active surveillance and those needing definitive intervention.
