摘　　要：目的探讨低场强磁共振成像(MRI)应用短时反转恢复(STIR)序列对脊柱转移瘤的诊断价值。方法回顾性分析34例脊柱转移瘤的MRI表现及相关临床资料。结果(1)34例共检出141个椎体转移。(2)STIR像上5例为等高混杂信号,29例为高信号。结论STIR在低场强MRI诊断脊柱转移瘤中,对早期发现病灶及了解肿瘤的侵袭范围、脊髓受累情况具有重要的意义。Objective To investigate the capability of low field intensity MR imaging using short T1 inversion recovery(STIR) sequence in diagnosing spinal metastasis.Methods MRI features of spinal metastases on STIR images in 34 patients were analyzed retrospectively.Results 141 metastatic lesions in 34 patients were detected with STIR sequence of low field intensity MRI.On STIR images,metastatic lesions of 5 cases were iso-high,mixed intensity while those of other 29 cases were hyperintense.Conclusion STIR sequence of low field intensity MRI has high capabilities in detecting early lesions and invasive extents of spinal metastases or revealing involvement degrees of spinal cord.
