中文摘要:

  研究脊髓损伤的MR表现。采用GESigna0．5T超导型磁共振检查机，用脊柱表面线圈，对55例脊柱创伤病人做MR检查。所有病例做轮位和矢状位检查，用自旋回波序列和快速自旋回波序列。脊髓损伤表现为脊髓水肿23例次（41．8％），髓内出血10例次（18．1％），脊髓不完全性和完全性断裂7例次（12．7％），椎间盘值22例次（364％），脊柱韧带断裂30例次（545％）。脊髓损伤多见于爆裂型和骨折脱位型脊柱骨折。MR是脊髓损伤最有效的检查方法，MR对发现和评估脊髓损伤优于CT扫描。

英文摘要:

  The purpose of this study was to evaluate MR imaging of spinal cord injury. Flfty-five patients for spinal MR imaging were examined with axial and sagittal spin-echo and fast spin-echo imaging. All imaging was per formed on a 0. 5T superconducting system
