摘要
目的:探讨MRI在早期腕关节类风湿性关节炎临床诊断中的应用。方法:回顾性分析2010年11月-2018年11月在我院治疗的31例早期腕关节类风湿性关节炎患者的临床资料,均根据临床症状及各项实验室检查确诊,分别行MRI和CT检查,将MRI检查结果作为观察组,将CT检查结果作为对照组,比较两组的诊断准确率、各项影像学特征的检出率、灵敏度、特异度及准确度。结果:观察组诊断准确率为93.55%,明显高于对照组的80.65%(P<0.05);两组在腕关节、掌手关节及近端指关节的骨质或软骨侵蚀破坏,关节腔积液,骨髓水肿等病例特征的检出率相当(P>0.05),观察组在滑膜增厚、肌腱炎、血管翳强化等病例特征的检出率明显高于对照组(P<0.05);观察组在滑膜增厚、骨髓水肿、骨侵蚀、关节腔积液、肌腱炎、血管翳强化等的灵敏度、特异度及准确度均明显高于对照组(P<0.05)。结论:MRI在早期腕关节类风湿性关节炎临床诊断效果显著,诊断准确率高,对各个病理特征的灵敏度、特异度及准确度高,有利于临床的诊断和病情评估,具有积极的临床意义。
Objective:To investigate the application of MRI in the clinical diagnosis of early rheumatoid arthritis of the wrist.Methods:A retrospective analysis in November 2010-November 2018 in our hospital treatment of 31 cases of early wrist li rheumatism lead of the clinical data of patients with rheumatoid arthritis,according to clinical symptoms and laboratory examination,diagnosis line of MRI and CT examination respectively,the results of MRI as observation group,the results of CT examination as control group,compared two groups of diagnostic accuracy,the imaging characteristics of detection rate,accuracy and sensitivity,specific degrees.Results:The diagnostic accuracy of the observation group was 93.55%,significantly higher than 80.65%of the control group(P<0.05).The detection rates of bone or cartilage erosion and destruction,joint cavity effusion and bone marrow edema in the wrist,metacarpal and hand joints and proximal finger joints of the two groups were similar(P>0.05).The detection rates of synovial thickening,tendonitis and pannus enhancement in the observation group were significantly higher than those in the control group(P<0.05).The sensitivity,specificity and accuracy of synovial thickening,bone marrow edema,bone erosion,joint cavity effusion,tendonitis and pannus enhancement in the observation group were significantly higher than those in the control group(P<0.05).Conclusion:MRI has a significant clinical diagnosis effect in the early stage of rheumatoid arthritis of the wrist,with high diagnostic accuracy,high sensitivity,specificity and accuracy for each pathological feature,which is conducive to clinical diagnosis and condition evaluation,and has positive clinical significance.
