The purpose of this study is to determine the ability of functional MRI techniques \[High Resolution Dynamic Contrast Enhanced MRI (HR-DCE-MRI), diffusion weighted MRI (DWI) and BOLD MRI\] to detect, measure and locate intra-prostatic cancer. 70 patients undergoing MRI for staging of prostate cancer prior to radical prostatectomy will be studied. Results of MRI obtained prior to surgery will be correlated with pathologic specimens to determine MRI accuracy.
