Abstract： 目的研究类风湿性(rheumatoid arthritis,RA)腕关节炎MRI表现及临床对比应用的价值.方法搜集符合1987年美国风湿病协会(ARA)诊断标准的RA患者50例,男15例,女35例,行双腕关节MR扫描.均采用常规SE T1WI、短时反转恢复(STIR)序列、增强T1WI行冠状面扫描.选取10例正常志愿者对照.同时搜集患者的临床症状、体征、实验室指标与MRI表现进行对比分析.结果 50例患者,MRI下均可见滑膜增厚、血管翳增生,38例血管翳可见MRI增强表现,骨髓水肿21例,关节积液37例 ,骨质破坏37例. 骨髓水肿组、关节积液组、血管翳强化组分别与无相应表现组在红细胞沉降率、健康评估问卷(HAQ评分)、患者的整体评估(AIMS)、肿胀关节数进行对比分析,差异均有显著性意义(P值均<0.001).骨髓水肿组与无骨髓水肿组的骨质破坏、跖趾关节(MTP)压痛、抗核周因子(APF)间差异均有显著性意义(P值分别为0.024、0.025、0.018).结论 MRI能够显示类风湿性关节炎的病理改变,通过MRI表现与临床对比研究,MRI在类风湿性腕关节炎的诊断及预后评价方面有一定应用价值.
