摘要
目的评价ＭＲＩ对脊椎转移癌早期诊断的价值。方法回顾分析１３例脊椎转移癌的ＭＲＩ资料，并与其他影像资料比较。结果全部患者ＭＲＩ均有明显异常；Ｘ线平片仅６例显示明显骨破坏；４例同时行ＣＴ检查者仅１例明确诊断为转移癌；４例同时行核素骨扫描检查，在两者能同时显示的脊柱区域，骨扫描异常区ＭＲＩ信号均有改变，另２例患者共５个椎体ＭＲＩ信号有局灶改变而骨扫描无异常。结论ＭＲＩ是诊断脊椎转移癌的一种敏感的影像方法。
Objective To evaluate the value of MRI on the
early diagnosis of spinal neoplasm metastasis. Methods The MRI data of 13 cases of the
disease was analysed retrospectively and was compared with other imagings. Results The
involved vertebrae had MRI signal changes in all patients diagnosed as spinal metastasis, but
plain radiographs showed that only 6 patients had obvious bone destruction, 4 patients had CT
examined at the same time, but only one showed the evidence of metastasis. All 4 patients who
had radionuclide bone scanning examined had obvious signal abnormality of vertebrae. In
addition, 5 positive vertebrae on MRI in 2 patients were negative on bone scan. Conclusion
MRI is a sensitive method for the diagnosis of spinal metastasis of cancer.
