Image Guidance Strategy in MRI-monitored Prostate Biopsy

Abstract

A method to use pre-surgical T2-weighted magnetic resonance images (MRI) with intra-surgical T 1-weighted MRI to guide prostate biopsy is presented. The method uses Tl-weighted MRI to guide the needle through the perineum, whilst T2-weighted MRI presented by a surgical navigation software was used to visualize a tumor foci and sextant targets. Two feasibility studies in an open-configuration MRI scanner indicated it is feasible to perform sextant and targeted prostate biopsies under MRI guidance.
