腰椎间盘退变中终板骨软骨炎的低场磁共振成像表现及临床意义

Low-field MRI findings of end-plate osteochondritis in lumbar disc degeneration and their clinical significance

目的探讨腰椎间盘退变中终板骨软骨炎的低场磁共振成像(MRI)表现及其临床意义。方法回顾性分析484例腰椎间盘退变患者的低场MRI表现,分析终板及其邻近骨质的信号改变。结果 484例腰椎间盘退变患者中148例伴终板骨软骨炎(30.6%),共累及283个终板,多发者121例(81.8%);多表现为一个退变椎间盘相邻椎体终板同时受累,按照不同的MRI表现,可将终板骨软骨炎分为4型。结论终板骨软骨炎是造成临床腰痛的原因之一,MRI对终板骨软骨炎能作出正确诊断,是检查该病的最佳方法。

Objective To investigate the low-field MRI findings of end-plate osteochondritis in disc degeneration and their clinical significance.Methods The low-field MRI findings in 484 cases of end-plate osteochondritis in disc degeneration were retrospectively analyzed,and the signal change of the end-plate and its adjacent vertebral bones was measured and analyzed.Results Among 484 cases of lumbar disc degeneration,end-plate osteochondritis was identified in 148 cases（30.6%）,involving 283 end-plates.Multiple end-plate osteochondritis was in 121 cases（81.8%） mainly manifested by one degeneration disc.Based on lesion′s signal intensity on MRI,end-plate osteochondritis was classified into 4 types.Conclusion End-plate osteochondritis is one of the reasons causing clincal lubar pain,MRI can clearly demonstrate the end-plate osteochondritis and make a correct diagnosis,which is the best method to detect this disease.
