There is preliminary evidence suggesting that MultiParametric Magnetic Resonance Imaging (MP-MRI) can be a marker for prostate cancer (PCa) aggressiveness and could be used to plan treatment. Gleason grade (GG) is a critical predictor of the aggressiveness of PCa, but in up to one in three men, the histology of radical prostatectomy specimens is different from the histology of Transrectal Ultrasound (TRUS)-guided biopsies. This discrepancy contributes to- and is a sign of- poor risk stratification of men with localised PCa.
