Thirty-five patients with clinically localized prostate cancer both underwent preoperative 3T T2-weighted endorectal coil MR imaging and real-time gray-scale tissue harmonic imaging transrectal ultrasound. Two readers independently scored all data sets. 3T ERC MR imaging achieved a significantly higher local prostate cancer staging performance compared with transrectal ultrasound. Also, for the most experience reader, sensitivity was significantly higher.
