目的 分析多层螺旋CT(MSCT)、 磁共振成像(MRI)及二者联合在诊断腰椎 体压缩性骨折中优劣势。方法 选取我院 2014年2月至2016年2月腰椎体压缩性骨折 患者93例，对患者分别进行MSCT、MRI及 联合诊断，分析患者骨折范围及分布结 果，分析腰椎压缩性骨折的MSCT及MRI影 像表现，比较MSCT、MRI及二者联合在诊 断腰椎体压缩性骨折的检出率。结果 经 MSCT诊断发现新鲜腰椎压缩性骨折与陈 旧性腰椎压缩性骨折比较在骨折线清晰锐 利、脊髓挫伤出血、脊椎旁软组织影、附 件骨折、椎体周围脏器挫裂伤、椎间盘真 空征象、椎体骨小梁结构紊乱硬化等方面 均具有显著差异(P＜0.05)；MRI和MSCT 联合MRI对腰椎体压缩性骨折的检出率较 MSCT的检出率高(P＜0.05)。结论 MSCT在 诊断腰椎体压缩性骨折中发挥着重要作 用，MRI能反映脊髓及韧带的损伤，MSCT 与MRI联合诊断更能提高诊断的准确性。

Objective To analyze the advantages and disadvantages of multi-slice spiral CT (MSCT), magnetic resonance imaging (MRI) and the combination of the two in the diagnosis of lumbar vertebral compression fractures. Methods Ninety-three patients with lumbar vertebral compression fractures treated in our hospital between February 2014 and February 2016 were studied. MSCT, MRI and combined diagnosis were performed in the patients. The range and distribution of fractures were analyzed. MSCT and MRI findings of lumbar vertebral compression fractures were also analyzed. The detection rates were compared betweeb MSCT, MRI and the combination of the two in the diagnosis of lumbar vertebral compression fractures. Results The MSCT diagnosis found that there were significant differences in clear and sharp fracture line, spinal cord contusion and hemorrhage, paravertebral soft tissue shadow, appendix fractures, contusion of vertebral body surrounding organs, intervertebral disc vacuum signs, disorder and sclerosis of vertebral trabecular bone structures between fresh vertebral compression fractures and oboslete lumbar vertebral compression fractures (P<0.05). The detection rates of MRI and MSCT combined with MRI in lumbar vertebral compression fractures were higher than that of MSCT (P<0.05). Conclusion MSCT plays an important role in the diagnosis of lumbar vertebral compression fractures. MRI can reflect the spinal cord and ligament injury. The combined diagnosis of MSCT and MRI can improve the accuracy of diagnosis
