目的 探讨MRI扫描对右膝关节 滑膜骨软骨瘤病的临床诊断价值。方 法 回顾性分析我院2013年1月-2016年1 月期间诊断的44例右膝关节滑膜骨软骨 瘤病患者的MRI扫描影像资料，并对患者 的MRI影像特征以及临床表现进行综合分 析。结果 44例患者MRI检查有38例患者 表现为关节内游离体，6例表现为滑膜明 显增生呈结节状，并可见滑膜内结节信 号略低。44例患者均可见程度不同的滑 膜增厚及量不等的关节积液。结论 MRI扫 描在对右膝关节滑膜骨软骨瘤病的诊断 过程中，能清楚地显示出骨软骨瘤的形 态、大小，还能够显示有无滑膜增厚及 关节积液，具有重要的临床应用价值。

Objective To investigate the clinical value of the MRI scan in the clinical diagnosis of right knee joint synovial membrane osteochondroma. Methods Retrospectively analyze of 44 cases of right knee joint synovial membrane osteochondroma patients MRI scan image data from January 2013 to January 2016, and comprehensively analyze the MRI scan characteristics. Results According to diagnosis, among 44 patients, there are 38 cases of intra-articular loose bodies, 6 cases of synovial nodules obvious hyperplasia, and slightly less visible within the synovial nodules signal. 44 patients were all visible degree of synovial thickening and the amount of joint effusion. Conclusion MRI scans can clearly show the osteochondroma morphology, and size in the diagnosis of right knee joint synovial osteochondroma disease process, will also be able to show any synovial thickening and joint effusion, has important clinical value.
