摘　　要：目的：探讨脊柱转移瘤的ＭＲＩ诊断及ＳＰＩＲ技术在ＭＲＩ诊断中的价值。材料和方法：回顾４０例经临床、病理证实的脊柱转移瘤的资料，分析肿瘤的ＭＲＩ征象，并与Ｘ线平片、ＣＴ、核素骨扫描作一对照。结果：脊柱转移瘤的ＭＲＩ表现为受累椎体信号异常、变扁膨出、多椎体受累、跳跃征、椎间隙扩大，多累及椎弓根、椎间盘不受侵犯。ＭＲＩ尤其是ＳＰＩＲ技术的应用较Ｘ线平片（５／１８）、ＣＴ（３／５）、核素骨扫描（８／１９）更敏感地显示病灶。PURPOSE:To study MRI diagnosis of vertebral metastases and to evaluate the SPIR techique on MRI. MATERIALS and METHODS:We analysed MRI apparance of 40 patients, clinical and pathologically proved vertebral metastases,and compared the sensitivities of MRI and plain radiograph, CT and radionuclide bone scans in detecting vertebral metastases. RESULT: On MRI, the vertebral metastases presented as adnormal signal intensity, flatted and expansion in the involved vertebral, non-continuous sign of multiple metastases, expanded intervertebral space, involvment of pedicle of vertebral arch and no involvement of intervertebral disc. MRI has a higner sensitivity in detecting vertebral metastases than plain radiograph,CT and radionuclide bone scans,especially when it used with SPIR technique.
