类风湿关节炎腕关节病变X线和MR影像对比观察

Comparison of Radiographs and Magnetic Resonance Imaging in the Detection of Carpal Lesions in Patients with Rheumatoid Arthritis

目的比较观察磁共振成像和X线平片在检查类风湿关节炎腕关节病变中的作用。方法选取25例类风湿关节炎患者,其中男5例,女20例,年龄20~75岁,平均46岁,在一星期内进行腕关节X线检查和MR检查。结果 25例临床诊断为类风湿关节炎的患者的50个腕关节中,X线发现14个腕关节有骨侵蚀的表现,MR发现45个腕关节有骨侵蚀的表现。MR检查一共发现156个腕骨的骨侵蚀病灶,而X线平片只发现18个腕骨的骨侵蚀病灶。在检查类风湿关节炎骨质侵蚀的病变上,两种检查方法之间的分析,统计学差异非常显著(P<0.001)。

Objective to compare the effects of magnetic resonance imaging and X-ray examination in the diagnosis of wrist joint lesions in rheumatoid arthritis. Methods a total of 25 patients with rheumatoid arthritis,including 5 males and 20 females,aged 20-75 years,with an average age of 46 years,underwent X-ray examination and MR examination within a week. Results in 50 wrist joints of 25 patients with rheumatoid arthritis,X-ray findings of 14 wrist joints showed bony erosions. MR revealed 45 wrist joints showing bony erosions. MR examination revealed a total of 156 bony erosions of the carpal bones,whereas only 18 bony lesions of the carpal bones were found on X-ray films. In examining the lesions of rheumatoid arthritis,there was a statistically significant difference between the two methods(P<0.001).
