类风湿腕关节的X 线与磁共振影像对比研究

目的 探讨类风湿性腕关节的Ｘ线与磁共振成像的诊断价值。方法 分析８例类风温性关节炎患者和１例正常人的腕关节Ｘ线片和ＭＲＩ，ＳＥ序列Ｔ１ＷＩ和Ｔ２ＷＩ及Ｇｄ－ＤＴＰＡ进行对比研究。结果 Ｘ线平片示８例患者均有腕关节软组织肿胀，６例骨质稀疏，骨囊状破坏，并节间隙窄，２例无异常改变；ＭＲＩ示８例均可见不同程度范围的血管翳，滑膜炎及韧带，肌腱损伤，而骨皮质破坏无法观察。结论 ＭＲＩ在提供病变炎怀过程，如滑膜炎，关节积液，肌腱滑膜炎等的变化优于Ｘ线片；对早期和活动期关节敏感性高，是很用的诊断方法。

A Study Comparing Radiography and MRI on Wrist Joints in Patients with Rheumatoid Arthritis

Objective To study the diagnostic value of X\|ray film and MRI on wrist joints in patients with rheumatoid arthritis. Methods Eight cases of wrist joints with RA and one normal wrist joint examined by radiograph and MRI were comparatively studied. Results Of 8 cases during the study,on radiograph all showed swelling soft tissues,6 cases showed bone cortical decalication,bone erosions,joint swollens and 2 cases had normal findings;On MRI all demonstrated different size and extent of synovitis,pannus and tenosynovitis and erosions,but the disruption of the cortex was diffcult to assess.Conclusion MRI yields excellent information about inflammatory process such as synovitis,joint effusions and tenosynovitis,and is more sensitive markers of early arthritis than X\|ray film and appears to be a useful diagnostic tool with suspected early arthritis and active arthritis.
