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.
