Our initial experience using a dedicated interventional MR suite featuring a 1.5T short bore MR scanner with wide aperture is discussed. We describe our techniques, equipment, imaging and planning protocols as well as results with a focus on our approach to MR-guidance to percutaneous biopsies using real-time imaging (<2s) or intermittent scanning (<6s). We found that using the T2-W and T1-W contrast mechanisms, we could perform procedures without the need for contrast agent.
