Prostate carcinoma (PCa) is one of the most common male cancers in the western world. While digital rectal examination, prostate-specific antigen (PSA) testing and transrectal ultrasound-guided biopsies are still the primary tools for prostate diagnostics, multiparametric MRI has an emerging role in both imaging diagnostics and procedural guidance. The purpose of this work is to present a virtual real-time navigation option for transrectal MRI-guided prostate biopsies, to estimate the targeting accuracy, and to report on the preliminary clinical experience.
