中文摘要:
  目的:探讨颈髓急性损伤后磁共振波谱(1H-MRS)的诊断价值。方法:对19例急性颈髓损伤患者根据神经功能分为完全性损伤及不全性损伤两组,选取创区与创区头侧远端颈髓行1H-MRS,半定量分析氮-乙酰门冬氨酸(NAA)、胆碱(Cho)、肌酸(Cr)和乳酸(Lac)含量的比值。结果:颈髓完全性损伤组中NAA/Cho、NAA/Cr显著减低,Lac/Cho显著增高,其创区头侧远端Lac/Cho含量也增高(P<0.05);不完全损伤组中仅Lac/Cho含量增加,头侧远端乳酸含量亦增高(P<0.05)。颈髓损伤不同程度组间NAA/Cho、NAA/Cr有显著性差异(P<0.05)。结论:1H-MRS所测NAA/Cho、NAA/Cr从代谢水平反映颈髓损伤的不同程度,创区头侧远端Lac/Cho比值增高提示颈髓隐匿损伤的存在。
