摘　　要：目的比较cT与MRI两种影像学检查方法应用于脊柱外伤诊断的临床价值。方法对41例脊柱外伤患者的脊柱CT扫描与MRI检查的影像资料进行回顾性分析并进行比较。结果4l例患者中，MRI检查显示41例发生脊柱骨折，CT显示38例发生骨折；MRI检查显示10例发生骨挫伤，CT检查无1例发生骨挫伤；MRI检查显示15例发生前纵韧带损伤，12例发生后纵韧带损伤，CT检查发现前纵韧带和后纵韧带损伤各2例，MRI检出率明显高于CT（P〈0．05）。CT检查发现120块碎骨片，MRI检查发现83例碎骨片，两组差异有统计学意义（P〈0．05）。结论CT和MRI为脊柱外伤的两种常用的影像学检查手段，各有优劣势，CT检查对碎骨片移位等情况可以清楚显示，MRI对韧带损伤，骨挫伤等可清楚显示，对于一般压缩性骨折可首选MRI检查，对于粉碎性骨折应加做CT检查了解碎骨片移位情况，以指导临床治疗方案的选择。Objective To analyze the diagnostic value of CT and MRI in spinal trauma. Methods 41 cases of spinal trauma in patients with spinal CT scan and MRI image data were retrospectively analyzed and compared. Results MRI examination revealed 41 cases of spinal fractures, CT showed 38 cases of fracture ; MRI examination revealed 10 cases of bone contusion, CT scan found 1 case of bone contusion;MRI examination revealed 15 cases of anterior longitudinal ligament injury, 12 cases occurred posterior longitudinal ligament injury, CT scan found that the anterior longitudinal ligament and posterior longitudinal ligament injury of 2 cases of MRI detection rate was significantly higher than CT（P 〈 0.05）. 120 bone chips CT findings, MRI examination revealed 83 cases of bone chips,the differ- ence was statistically significant （P 〈 0.05 ）. Conclusion CT and MRI of spinal trauma are two commonly ways of imaging examination. There are advantages and＂ disadvantages of CT examination of the bone chips shift and so can be clearly shown MRI for ligament injury. Bone contusion can be clearly demonstrated for the general compression fractures in MRI examination. Commimcted fracture should be added to do a CT scan.
