目的：研究脊柱转移瘤的MRI特点。材料和方法：分析29例脊柱转移瘤的MRI图像。结果：表现为溶骨型者65．5％、成骨型10．3％、混合型24．1％、附件破坏者高达69％、谁管受累者69％、椎间孔狭窄者58.6％、椎体病理骨折者79．3％、椎旁肿块或软组织受侵者44．8％。结论：作者认为脊柱转移瘤有较特征性的MRI表现，结合临床资料可以与其它疾病相鉴别。
Objective: To study the MRI features of spinal metastases. Materials and Methods: MRI images of 29 cases of spinal metastases were analyzed. Results: 65.5% of osteolytic bone types, 10.3% of osteoblastic types, 24.1% of mixed types, 69% of damaged appendages, 69% of those who suffered from tube involvement, and 58.6% of patients with intervertebral foramen stenosis. 79.3% of the vertebral pathological fractures, 44.8% of paravertebral masses or soft tissue invaders. Conclusion: The author believes that the spinal metastases have more characteristic MRI features, and can be differentiated from other diseases in combination with clinical data.
