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。

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 accuracy of lateralization was proved by surgery, electrocorticography ( EcoG), and depth electroencephalography ( DEEG) in 12 out of the 20 cases.
