摘　　要：目的:为了提高脊椎转移瘤诊断及其与其他椎体病变的鉴别诊断水平。方法:回顾性分析经病理证实的转移瘤79例和误诊病例15例的MRI特点,归纳其影像表现的差异。结果:79例转移瘤中,累及椎体125个,多为跳跃式分布;累及附件骨92个,占73.6%;椎体破坏变形81个,占64.8%;椎间盘均无变化;有软组织肿块22例(17.6%),软组织肿块常以破坏区为中心生长。T1WI均呈低信号,T2WI信号改变可以多种多样。结论:MRI检查在诊断脊椎转移瘤及与其他脊椎病变的鉴别诊断中更敏感、更具特异性。Objective：To investigate the MRI features and improve differential diagnosis of the spinal metastasis. Methods： The MRI features of 79 cases of the spinal metastasis were analysed retrospectively and concluded the different MRI features. Results： There were 79 cases in 125 vertebral bodies with metastasis and those lesions usually appeared ＂jump sign＂;92 appendixes were involved（73.6%）;81 vertebral bodies were destroyed and metamorphosed（64.8%）. All the ntervertebral discs didn＇t been involved. There were soft-tissue masses in 22 cases （17.6%）. Soft tissue mass was always around the focus of destruction. MRI signal of the lesions in vertebral body demonstrated decreased on TIWI and complex variation on T2WI. Conclusion： The low field MRI is sensitivity in detecting the spinal metastasis and helpful in differential diagnosis in spinal metastasis.
