| 摘要: |
| ［目的］探讨MRI在滑膜软骨瘤病中的临床诊断价值。［方法］回顾分析经病理证实的15例滑膜软骨瘤病患者的X线及MRI影像资料，并与Milgram病理分期对照，其中膝关节7例，髋关节5例，肘关节、肩关节及踝关节各1例。［结果］滑膜软骨瘤病的MRI表现为滑膜增厚、关节内游离体、关节积液和关节退行性改变。不同时期的滑膜软骨瘤病的MRI表现不尽相同，Milgram Ⅰ期患者X线平片阴性，MRI显示滑膜的结节状增厚和软骨化生倾向；MilgramⅡ、Ⅲ期的患者除滑膜增厚外，关节内游离体表现为软骨结节和骨性结节，结节表面可有强化。［结论］MRI检查可以提供更多关节内游离体和滑膜病变的信息，对于滑膜软骨瘤病的诊断和分期提供帮助，特别是对X线检查阴性的Milgram Ⅰ期病例具有重要价值。 |

| Abstract: |
| ［Objective］To investigate the clinical value of magnetic resonance imaging (MRI) in synovial chondromatosis.［Methods］Fifteen patients with histologically confirmed synovial chondromatosis underwent imaging and X ray examinations.Among these patients,there were 7 knee joints,5 hip joints,1 elbow joint,1 shoulder joint and 1 ankle joint.［Results］MRI clearly showed thickened synovium,free bodies,joint effusion and joint degenerative lesions.The MRI manifestation of synovial chondromatosis varied with stages.For the Milgram-I stage cases,without positive features in plain film.MRI was superior to X-ray in showing the number and position of free body and synovial lesions in the cases of cartilaginous.［Conclusion］MRI provides much more information about free body and synovial lesions,which is useful especially in the diagnosis of Milgram-I stage cases that is negative in X-ray examination. |
