Multiparametric MRI has been shown to improve the detection and localization of prostate cancer and is therefore ideally suited for targeting as well. While biopsy guidance in an MRI system typically requires more efforts and time (30‑120 min) than under ultrasound imaging, MRI provides unparalleled contrast of the prostate substructures. Diagnostic detection rates show large variability between patient groups and sites (about 10-60%). With a custom-made navigation option for a commercial device, any intraprocedural MRI data can be used for stereotactic real-time biopsy targeting. This work presents navigation features, indications and clinical biopsy results for a total of 75 patients.
