Accuracy of endorectal magnetic resonance/transrectal ultrasound fusion for detection of prostate cancer during brachytherapy.

Objective: To evaluate the effectiveness of 3 Tesla endorectal magnetic resonance imaging (erMRI) with fusion to real-time transrectal ultrasound to detect a dominant cancer focus within the prostate gland.

Materials And Methods: The safety and effectiveness of identifying suspicious lesions using erMRI was assessed in men undergoing brachytherapy perineal implants. Suspicious lesions identified on erMRI fused to real-time transrectal ultrasound were biopsied at brachytherapy seed placement.
