Real-time MR-guided joint puncture and arthrography: preliminary results

The purpose of this study was to evaluate interactive MR-guided joint punct ure with intra-articular application of contrast agent. MR-guided arthrogra phy of the shoulder joint was successfully performed in three patients usin g an interactive guidance-system implemented in an open-configuration MR sy stem. Visualization of the needle pathway and contrast inflow was comparabl e to that with conventional X-ray fluoroscopy. The position of the intra-ar ticular needle tip was accurately confirmed and subsequent MR arthrography was diagnostic in all cases.
