目的通过对膝关节滑膜骨软骨瘤病的DR、CT、MRI的影像表现分析,总结探讨其诊断价值。方法搜集整理22例有病理结论的膝关节滑膜骨软骨瘤病患者的影像资料,进行汇总研究。结果 22例DR检查者中16例可见游离体,能明确诊断;17例CT检查患者中16例明确诊断;11例MRI检查者中不仅能观察游离体,还可测定滑膜不规则增厚的程度及关节囊腔的扩张情况。结论 DR对膝关节滑膜骨软骨瘤病多能作出诊断,是必要的影像学检查;CT对游离体的显示明确,是手术时首要参考;而MRI是滑膜骨软骨瘤病早期诊断的重要方法。
Objective To analyze the imaging manifestations of DR, CT and MRI of synovial osteochondromatosis in knee joint and to discuss its diagnostic value. Methods Collecting the image data of 22 patients with synovial osteochondromatosis with pathological findings and conducting a summary study. Results Twenty-two of the 22 DR patients were diagnosed as free and could be diagnosed clearly. Sixteen of the 17 patients with CT were diagnosed correctly. Among the 11 patients who underwent MRI examination, not only free bodies but also irregular thickening of the synovium Extent and expansion of joint capsule cavity. Conclusions DR can diagnose synovial osteochondromatosis multiple and can be used to diagnose synovial osteochondromatosis. CT is a necessary imaging examination. CT is a clear indication of free body and is the primary reference for surgery. MRI is important for the early diagnosis of synovial osteochondromatosis method.
