摘要
目的:研究剥脱性骨软骨炎(OCD)的MRI表现。方法:回顾性分析40例经膝关节镜及手术证实的剥脱性骨软骨炎MRI影像资料。评价剥脱性骨软骨炎的MRI特点。结果:OCDMRI表现为关节承重部位软骨下骨质缺损区。40例OCDMRI表现可分为Ⅵ型:Ⅰ型4例,Ⅱ型13例,Ⅲ型12例,Ⅳ型3例,Ⅴ型7例,Ⅵ型1例。结论:OCD在MRI有特征性表现,MRI对其可作出明确诊断。
Objective：To study MRI manifestations of osteochondritis dissecans. Methods：40 cases with osteochondritis dissecans proved by arthroscopy and operation were reviewed and their MRI findings were analyzed retrospectively. Results：The femoral condyle was the most commonly affected place in the knee. 40 cases were classified into several types： 4 cases of type Ⅰ ,13 type Ⅱ ,12 type Ⅲ ,3 type Ⅳ ,7 type Ⅴ and 1 type Ⅵ. Conclusion：Osteochondritis dissecans has specific MRI manifestations which are much helpful to the diagnosis.
