摘　　要：目的探讨MRI在评价急性脊髓损伤中的临床应用价值。方法收集急性脊髓损伤患者50例，行同期X线片、CT和MRI检查，MRI检查应用1．5T超导型磁共振成像仪，采用自旋回波序列和快速自旋回波序列，常规矢状位及横轴位扫描，17例加扫冠状位。结果脊髓水肿：MRI检出16例，CT检出4例；脊髓挫伤出血：MRI检出21例，CT检出11例；脊髓受压变形：MRI检出34例，CT检出15例；脊髓断裂：MRI检出10例，CT检出3例。X线片未检出上述脊髓损伤。结论MRI对评估脊髓损伤明显优于X线片和CT扫描，是急性脊髓损伤的最佳检查与诊断方法。Objective To assess the clinical value of MRI in evaluation of acute spinal cord injury. Methods A total of 50 patients with acute spinal cord injury were examined with magnetic resonance （ MRI）, X-ray and CT. Of all, 15 patients for spinal MR imaging were examined with axial and sagittal spin-echo and fast spin-echo imaging and 17 with coronal imaging. All imaging was performed on 1.5T superconducting system （GE/SIEMENS） with spine surface coil. Results Among 50 patients with acute spinal cord injury, spinal cord edema was detected by MRI in 16 patients, by CT in four but none by X-ray. Intraspinal cord hemorrhage was detected by MRI in 21 patients, by CT in 11 but none by X-ray. Compression and dislocation were detected by MRI in 34 patients, by CT in 15 but none by X-ray. Incomplete and complete transection of spinal cord was found by MRI in 10 patients, by CT in three but none by X-ray. Conclusion MRI is superior to CT scanning and X-ray in detection and evaluation of acute spinal cord injury and is the optimal method for examination and diagnosis of acute spinal cord injury.
