MRI在腕关节早期类风湿关节炎诊断中的价值

目的分析磁共振成像(MRI)在腕关节早期类风湿关节炎(rheumatoid arthritis,RA)诊断中的应用价值。方法回顾性分析33例经临床与生化检查证实早期类风湿关节炎患者的腕关节MRI表现。结果 58个腕关节滑膜受累,其中双侧受累25对,单侧受累8个,表现为滑膜增厚、T2WI信号增高,增强扫描明显强化;7例腕关节少量积液,8例腕关节构成骨骨质破坏、骨髓水肿等异常改变。结论 MRI在一定程度上反应早期RA的病理演变过程,是诊断腕关节早期RA、观察治疗效果的一项重要和可靠的检查方法。

Objective To analyze the clinic application value of MRI in diagnosis of early rheumatoid arthritis.Methods Retrospectively analyze the MRI imaging of 66 wrist joint of 33 early patients with rheumatoid arthritis confirmed by clinical and biochemical examination.Results Fifty-eight wrist joint synovial involved, including bilateral involvement of 25,unilateral involved 8,for the performance of the synovial thickening, T 2-Weight images showing signal high, the enhancement scannings showing obviously strengthened.Effusion was found in 7 cases of wrist joint. Bone destruction and marrow edema were found in 8 cases of wrist joint.Conclusion To some extent,MRI of wrist may reflect the early RA histologic changes .So, MRI is a important and reliable method for diagnosis and curative effect observation of wrist in early rheumatoid arthritis.
