Abstract:
Objective To discuss the application of 18F-FDG PET/CT in epileptogenic zone localization.Methods Tirty-two patients with epilepsies were studied with interictal 18F-FDG PET/CT cerebral imaging,and all of them had scalp EEG,CT or MRI results for comparision.Results The sensitivity of 18F-FDG PET/CT was 90.6%,27 patients(84.5%) showed focal hypometabolism,2 patients(6.3%) showed focal hypermetabolism and rest 3 patients(9.4%) had negative result.The sensitivity of EEG was 65.6%(21/32),the sensitivity of CT and MRI was 31.0%(10/32).Conclusion 18F-FDG PET/CT was a sensitive and accurate image modality in the localization of epileptic foci.
