类风湿性关节炎（RA）的分期和治疗反应的放射学评估是基于骨侵蚀、关节间隙狭窄和骨质疏松的存在。大多数RA分期的放射学方法缺乏观察者之间的相关性，并且耗时。磁共振（MR）成像提供了良好的描述软组织异常的关节受RA，这使得检测早期变化。对17例RA患者的19个关节进行了表面线圈MR成像研究。MR成像显示但平片上未清楚显示的可测量异常包括骨侵蚀、关节积液、滑膜鞘积液和软骨不规则和变薄。本组7例患者在金疗法前和6个月后进行了MR成像。4例患者在MR图像上有明显的间隔变化，而在平片上没有看到。MRI可能成为定量评价RA关节病变的敏感、客观的方法。
Radiologic assessment of the stage and treatment response of rheumatoid arthritis (RA) is based on the presence of bone erosions, joint-space narrowing, and osteoporosis. Most radiologic methods for staging RA lack interobserver correlation and are time consuming. Magnetic resonance (MR) imaging provides excellent depiction of soft-tissue abnormalities of the joints affected by RA, which allows detection of early changes. Nineteen joints of 17 patients with RA were studied with surface-coil MR imaging. Measurable abnormalities demonstrated by MR imaging but not clearly seen on plain radiographs included bone erosions, joint effusion, synovial sheath effusion, and cartilage irregularity and thinning. Seven patients of this group underwent MR imaging before and after 6 months of gold therapy. Four patients had significant interval changes on MR images that were not seen on plain radiographs. MR imaging may become a sensitive and objective method for quantitative assessment of the joint changes of RA.
