A retrospective study of 251 men who underwent prostate MRI prior to prostatectomy was performed. The addition of ADC and prostate volume to D'Amico risk classification performed better than D'Amico risk classfication alone in predicting high risk disease. Our results suggest that adding MR prostate volume and ADC to D'Amico classification may improve overall identification of high risk cancer.
