摘　　要：目的研究RA(类风湿关节炎)患者MRI信号差异在各序列表现的临床价值。方法回顾分析我院自2008年9月至2014年5月以来,于我科检查的73例RA患者临床资料作为研究组,对照组选择同时间段的65例健康志愿者,对研究组患者冠矢轴位分别进行扫描,对比信号差异。结果研究组患者早期实施动态增强MRI,腱鞘、血管翳、关节囊滑膜与对照组相较,均呈明显增厚表现(P<0.05);且两组各序列下MRI信号均存在差异(P<0.05)。结论 RA患者实施动态增强MRI,所测滑膜厚度、Slopemax、ERmax、TIC等指标,与早期MRI征象特点相结合,能够明确病理改变,并且不同序列下MRI信号,具有特征性表现及特点,这对RA的早期诊断、治疗、预后等,均有着非常重要的临床价值,应结合患者具体情况,给予推广。Objective To study the RA （rheumatoid arthritis） in patients with MRI signal differences in the sequence.Methods Retrospective analysis of our hospital from 2008 September to 2014 May, clinical data of 73 patients with RA in our department examination as the study group, and 65 cases of healthy volunteers were selected in the control group the same time period, the study group patients with parietal axial scans were performed comparing the signal difference.Results the study group patients with dynamic enhanced MRI, tendon, joint capsule synovial pannus, compared with the control group, both showed thickening performance （P〈0.05）,and the sequence of MRI signal were different （P〈0.05）.Conclusion Dynamic enhanced MRI implementation of RA patients, the synovial membrane thickness, Slopemax, ERmax, TIC and other indicators, combined with early MRI features, can clear the pathological changes, and different sequence of MRI signal, has the features and characteristics of RA, the early diagnosis, treatment, prognosis and so on, have a very important clinical value, should be combined with the specific circumstances of patients, given the promotion.
