目的探讨全脊柱MRI成像在转移瘤中的诊断价值。方法对2007年10月至2010年4月经临床证实的19例脊柱转移瘤患者行MRI成像,序列包括矢状位T_1WI、T_2WI扫描,在病变部位做横断位T_2WI扫描。结果 19例脊柱转移瘤中累及单个椎体2例,多个椎体受累17例;受累椎体部位颈段1例,胸段13例,腰段7例,骶段1例;转移瘤骨质异常表现包括溶骨性破坏、成骨性改变、混合型改变等。结论全脊柱MRI成像是脊柱转移瘤重要检查方法 。 Objective To investigate the diagnostic value of whole spinal MRI in metastatic tumors. Methods Totally 19 patients with spinal metastases who were clinically confirmed from October 2007 to April 2010 were included in this study. The sequences included sagittal T_1WI and T_2WI scans and T_2WI scan of the lesion. Results 19 cases of spinal metastases involved single vertebrae in 2 cases and multiple vertebral bodies in 17 cases. There were 1 case of cervical vertebrae, 13 cases of thoracic segment, 7 cases of lumbar segment, 1 case of sacral segment, Abnormal manifestations include osteolytic destruction, osteogenic changes, mixed changes and so on. Conclusion Spinal MRI is an important method for the diagnosis of spinal metastases.
