摘要 目的探讨磁共振波谱(MRS)在难治性癫痫诊治中的临床应用价值。方法对42例难治性癫痫患者和20例健康志愿者进行动态脑电图(EEG)、MRI和MRS检查。采用MRS检测双侧海马N-乙酰天门冬氨酸(NAA)、肌酸复合物(Cr)和胆碱复合物(Cho)的水平。结果①42例难治性癫痫患者中,14例MRI发现海马硬化,35例MRS异常。②与对照组相比,癫痫病侧组的NAA/(Cr+Cho)、NAA/Cr和NAA/Cho均显著降低;癫痫对侧组NAA/(Cr+Cho)、NAA/Cho低于对照组。③与对照组比较,海马硬化组(HS组)、非海马硬化组(NHS组)的上述3个指标均明显降低,HS组的上述3个指标均低于NHS组。结论 MRS检查在难治性癫痫的早期诊断和病灶定位方面比MRI具有更高的敏感性,可提高难治性癫痫患者海马生化异常改变的检出率。
