| 摘 要： | 目的探讨肩区类风湿性关节炎（RA）的低场（0.2T）四肢MRI表现。方法回顾性总结31例临床确诊，影像证实的肩部RA。34例普通关节病做对照。分析病变早期E—MRI特征。结果肩RAMRI阳性表现，滑膜增生血管翳形成（93.5％），骨侵蚀（77．9％），软骨侵蚀（90．3％）等，以滑膜和骨髓改变诊断肩RA，其敏感性、特异性、正确率分别为：69.0％、76．7％、72．3％。结论E—MRI对肩RA定位、定性和分期诊断具有重要价值。 |

| Abstract: | 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. |
