【摘要】 目的 探讨MRI对老年非外伤性脊柱压缩骨折的病因诊断。方法 回顾分析65例经临床病理证实的老年脊柱压缩骨折，分别观察分析椎体、椎间盘及附件的MRI形态、信号改变。结果 脊柱转移瘤36例，仅2.8%残余正常骨髓信号，骨折椎体后部或前后部均膨大，75%椎弓根受累。脊柱骨质疏松29例，100%骨折椎体内残余正常骨髓信号，椎体前后缘平直或稍内凹。结论 脊柱转移瘤、骨质疏松引起的脊柱压缩骨折各有其特征性的MRI表现，MRI是诊断老年非外伤脊柱压缩骨折病因有效的影像学方法。【关键词】 脊柱骨折；压缩骨折；磁共振成像

【Abstract】 Objective To investigate the diagnosis of causes of compression fracture of senile nontraumatic spine by MRI.Methods 65 cases of compression fracture of senile nontraumatic spine were observed.The MRI characters of compression fracture of vertebral bodies,the vertebral discs and accessory parts were evaluated.Results In 36 cases of metastatic tumor of spine,the signal intensity of normal bone marrow remained in only 2.8%.Enlarge posterior or anterior and posterior parts of vertebral bodies were demonstrated.The pedicle of vertebral arch were involved by 75%.In 29 cases of spinal osteoporosis,there were some residual normal bone marrow signal in all cases.The edge of anterior and posterior parts of vertebral bodies were straight or slightly concave.Conclusion The special MRI features of metastasis,and osteoporosis of spine are demonstrated.MRI is a useful method to diagnose causes of compression fracture of senile nontraumatic spin. ......
