The accuracy of lateralization was proved by surgery, electrocorticography ( EcoG), and depth electroencephalography ( DEEG) in 12 out of the 20 cases. 20例患者中,有12例经手术脑皮质电图(ECoG)、脑深部电图(DEEG)证实定侧准确;
Compared with ECoG or DEEG, the sensitivity and accuracy of PET to localize the epileptic foci were 92% and 87%. 与ECoG或DEEG相比,PET对致癎灶的检出灵敏度为92%,定位准确性为87%。
The scalp electroencephalogram ( EEG) was examined in all patients, among whom electrocortico-gram ( ECoG) or depth electroencephalogram ( DEEG) was examined in 26 cases and MRI and ( or) CT were performed in 66 cases. 所有患者均行头皮脑电图(EEG)检查,其中26例行皮层脑电图(ECoG)或深部脑电图(DEEG)检查;66例行脑MRI及(或)CT检查。
