One was found to have two high-grade lesions, bilaterally concordant on mpMRI and biopsy, at the posterior boundary of the prostate at mid-gland ( Figure 2A ). A second patient had a metallic total hip replacement which generated substantial imaging artifact in the region of the prostate and rectal wall interface ( Figure 2B ).
