摘　　要：目的探讨腰椎间盘退变伴终板骨软骨炎的低场MRI表现。方法搜集经MRI诊断腰椎间盘退变的MRI资料504例，其中148例共330个终板伴发终板骨软骨炎。分析终板及邻近椎体骨质信号改变，根据其信号特点分为4个类型。结果148例330个终板中，I型68个（20.6％），1I型53个（16.1％），Ⅲ型174个（52.7％），IV型35个（10.6％）。仅1个椎间盘的终板异常98例（168个终板），占66.2％，2个椎间盘42例（123个），占28.4％，3个以上椎间盘8例（39个），占5.4％。病变好发于下腰段。结论低场MRI能清楚地显示腰椎间盘退变及终板骨软骨炎，有利于腰痛疾病的及时诊治。Objective To investigate the diagnostic value of low-field MR imaging in lumbar disc degeneration with end-plate osteochondritis. Methods Imaging data of 504 patients with lumbar disc degeneration diagnosed by MRI were retrospectively analyzed. Among these cases, the total of 330 end-plate osteochondritis in 148 patients was found. According to MR signal findings of end-plate and it＇s adjacent vertebra, the lesions were classified as 4 types. Results 330 end-plates were involved in 148 patients, including type Iin 68（20.6%）,type Ⅱ in 53（16.1%）,type Ⅲ in 174（52.7%） and type Ⅳ in 35（10.6%）.Among all 148 patients, the end-plates at one lumbar disc, two disci and over three disci involved in 98 （66.2%）, 42 （28.4%） and 8 （5.4%）, respectively. The lesions were usually found in the lower lumbar vertebra. Conclusion MR imaging could accurately show the end-plate osteo- cbondritis and degenerative lumbar disc.
