Value of ¹⁸F-FDG brain positron emission tomography imaging and video-EEG in locating epileptogenic foci

Objective To explore the values of ¹⁸F-FDG brain PET imaging and video-EEG（VEEG） in localizing epileptogenic foci and their relation. Methods ¹⁸F-FDG brain PET imaging,VEEG,and intra-operative electrocorticography（EcoG） were performed on 42 patients with intractable epilepsy and their results were compared. Results Among the 42 patients,PET and VEEG showed abnormalities in 38（92.9%） and 37（89%） patients respectively,PET and VEEG showed identical lesions in 23 patients（54.8%） and partially identical lesions in 8 patients（19%）,PET and intra-operative EcoG showed identical lesions in 34 patients（80.9%） while VEEG showed identical lesions in 25（60%）. Conclusion ¹⁸F-FDG brain PET imaging is noninvasive,sensitive and more accurate than VEEG in locating epileptogenic foci.
