We demonstrate feasibility and report technical and clinical performance of a needle navigation system where pathologically referenced multi-parametric interventional MRI guidance improved the determination of tumor boundaries, and enabled accurate tumor-targeted HDR prostate brachytherapy. The value of 3D imaging to document actual location of biopsy cores in reference to anatomic boundaries is emphasized.
