In this feasibility study a safe, easy and precise instrument guidance using the POCC based sequence for automatic needle-guide tracking in transrectal 3 T MR-guided prostate biopsies was demonstrated. The combination of very easy handling, good tumor detection rates comparable with other MR-guided prostate biopsy techniques, use of standard, commercial available devices and short procedure times is very promising and making this approach attractive for clinical routine.
