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 in the early diagnosis of metastatic spinal cancer. Methods MRI data of 13 cases of metastatic spinal cancer were retrospectively analyzed and compared with other imaging data. Results All patients had significant MRI abnormalities; only 6 cases showed obvious bone destruction on X-ray plain film; 4 cases who underwent CT examination at the same time had only one case of definite diagnosis of metastatic cancer; 4 cases underwent simultaneous radionuclide bone scan in both cases. In the region of the spine that can be displayed at the same time, the MRI signal in the abnormal bone scan area was changed. In the other two patients, the MRI signal of 5 vertebral bodies had focal changes and there was no abnormal bone scan. Conclusion MRI is a sensitive imaging method for the diagnosis of metastatic cancer in the spine.
