分析２０例急性脊柱外伤的磁共振成像（ＭＲＩ）表现，并对１３例脊髓挫伤患者进行了临床随访。２０例均在伤后２周内行ＭＲＩ检查。脊髓挫伤１８例，挫伤脊髓段不同程度增粗，呈长Ｔ１和长Ｔ２信号，向脊髓头尾端延伸２～８个椎骨节段，其中８例有髓内出血，占４２％。ＭＲＩ尚发现１５例椎骨骨折，５例硬膜外出血，６例椎前软组织挫伤，６例外伤性椎间盘脱出和３例脊柱韧带撕裂。结果显示，ＭＲＩ是急性脊髓外伤最佳的影像学检查方法，其尚能很好检出椎体骨折和椎管内外软组织外伤性病变。脊髓挫伤有出血者，临床预后不良。
MRI findings of 20 cases of acute spinal trauma were analyzed. Thirteen patients with spinal cord contusion were followed up. All 20 patients underwent MRI examination within 2 weeks after injury. Spinal cord contusion in 18 cases, contusion of the spinal cord segments varying degrees of thickening, showing long T1 and long T2 signals, extending to the spinal cord head and tail 2 to 8 vertebral segments, of which 8 cases of intramedullary hemorrhage, 42%. MRI also found 15 vertebral fractures, 5 cases of epidural hemorrhage, 6 cases of preoperative soft tissue contusion, 6 cases of traumatic disc herniation and 3 cases of spinal ligament tear. The results show that MRI is the best imaging method for acute spinal cord injury, which can detect vertebral fractures and soft tissue traumatic lesions in the spinal canal well. Bleeding spinal cord contusion, the clinical prognosis is poor.
