Commonly, prostate cancer (PCa) is diagnosed using a random sample biopsy of the prostate under transrectal ultrasound guidance (TRUS). Multiparametric MRI increased detection rate, especially of smaller lesions. Since these lesions are difficult to target with conventional TRUS biopsy, MR-guided biopsy procedures have been established. Recent technical developments integrated MRI images with ultrasound with live fusion. Most of these techniques use a transrectal approach for the biopsy. In this study, we evaluated a MR/TRUS live fusion system with a transperineal biopsy approach. We found an excellent accuracy of targeting smaller lesions <0.5cc in a phantom model.
