目的探讨脊柱转移瘤的MRI诊断。方法回顾性分析128例临床资料完整的脊柱转移瘤的MRI表现。结果（1）信号异常：87.5%表现为T1W低信号，12.5%表现为T1W混合或等信号；（2）病灶多发80.5%，跳跃52.3%，附件破坏64.1%，其中并椎弓根膨大破坏57%；（3）椎旁软组织肿块31.3%。不破坏椎间盘；（4）合并压缩骨折52.3%，表现为“楔形”、“盘状”、“倒楔形”。结论脊柱转移瘤具有高灵敏性和较特异性的MRI表现。该法优于常规X线及CT检查。

Objective　To study the MRI diagnosis of spinal metastasis.Methods　The MRI appearances of 128 cases of spinal metastasis proved clinically were retrospectively analyzed.Results　(1)The MRI signal was T1WI low in 87.5% and 12.5% was mixed or equal.(2)Multi-focus in 80.5%.The "jump up sign"occurred in 52.3%,the accessory parts destructed in 64.1%,in which root of vertebral destructed with expanded in 57%.(3)The masses of paravertebral occurred in 31.3%.The disc of vertebral was not destructed.(4)The patients associated with vertebral compresion fracture such as "wedge","disc"or"wedge of rear"in 52.3%.Conclusion　The MRI findings of spinal metastasis is of high sensitivity and spectivity.The method is advanced than X-ray and CT.
