Objective To study the appearance of extremity magnetic resonance imaging of the rheumatoid arthritis(RA) in shoulder joint. Methods 31 cases with RA in shoulder joint which had been diagnosed clinically and radiologically were analyzed retrospectively, 34 cases with osteoarthritis were taken as control, early appearance of E-MRI of RA in shoulder joint were summarized. Results positive findings of MRI in shoulder joint as follow, synovitis and enhanced bilateral pannus (93.5%), bone erosion (77.9%), cartilage erosion (90.3%),change of synovium and bone marrow was taken as diagnostic standard, the sensitivity, specificity, accuracy, 69.0%、 76.7%、72.3%. Conclusion E-MRI have important value in the diagnosis of RA in shoulder joint.
