摘　　要：目的 MR脊柱转移瘤不同序列诊断价值进行比较。方法回顾性分析54例脊柱转移瘤在各序列信号及检出数。结果 54例患者平扫(包括714椎体)及强化扫描16例(包括190个椎体),1各序列受累椎体数目的计数资料的2检验中,T1WI与T2WI、T2WI与STIR、T2WI与增强扫描的分别配对对比的2检验中,P<0.01,差异有统计学意义;T1WI与增强扫描、STIR与增强扫描分别配对对比的2检验中,P>0.05,差异无统计学意义;2 T1WI、T2WI、STIR信号测量的计量资料统计的t检验中,T2WI的SD、SCR的P>0.05,差异无统计学意义。T1WI、STIR及增强扫描的SD、SCR的P<0.01,差异有统计学意义。结论 T1WI与STIR是诊断脊柱转移瘤的平扫的黄金序列。Objective In order to evaluate and analyze the diagnostic value of different sequence in MRI for spinal metas- tasis. Methods A retrospective analysis was performed that included 54 cases of spinal metastasis in each sequence signal and the detected number. Results As far as 54 patients with plain scan （including 714 vertebrae） and 16 patients with en- hanced scan （including 190 vertebrae） were concerned. ①There was a statistical significant diffrence （ P〈0.01） in the compairsion of TI WI and T2 WI, T2WI and STIR, T2 WI and enhanced scan respectively in χ^2 test of enumeration data in each sequence involved vertebral number; there was no statistically significant difference （ P〉0.05） in the compairsion of T1WI and enhanced scan, STIR and enhanced scanning respectively in χ^2 test of enumeration data in each sequence in- volved vertebral number;② There was no statistical significant difference （P〉0.05） in the compairsion of the SD, SCR of T2 WI in T test of the measurement data in signal measurement, otherwise there were statistical significant diffrences （ P〈0.01） in that of TlWI STIR and enhanced scan respectively. Conclusion TrWI and STIR sequence are the most val- ueable sequence in plain sequence for diagnosis of spinal metastasis.
