外科手术治疗难治性癫痫的价值已得到肯定，然而准确地识别致痫灶显得尤为重要，CT和磁共振显像（MRI）的诊断率仅30％～45％，而单光子发射型计算机断层摄影术（SPECT）脑灌注显像率可达75％～86％，这为外科手术治疗提供了精确定位的依据［1］。我们观察31例癫病患者脑局部血 The value of surgical treatment of refractory epilepsy has been affirmed, however, accurate identification of epileptogenic lesions is particularly important, CT and magnetic resonance imaging (MRI) diagnostic rate of only 30% to 45%, and single photon emission computed tomography Photographic (SPECT) cerebral perfusion imaging rate of up to 75% to 86%, which provides accurate surgical basis for surgical treatment [1].
