Can MR-US fusion targeted biopsy better characterize prostate cancer based on the degree of MR image suspicion compared to image blind (systematic random) biopsy? To use MR data in office urological practice, MR-US fusion biopsy is proposed.1'2 This requires image acquisition, segmentation, image fusion, US guided biopsy and confirmation of biopsy trajectory. There are potential errors in each of these steps. Since the MR fused lesion is only a virtual image, the fundamental question is whether the virtual lesion biopsied was even in fact the real MR lesion. TRUS is important because its image is real, not virtual. When the MR lesion is also visible on US, real-time US can precisely guide the needle, relying on the reality of the US image.
