Abstract: Surgical treatment of patients suffering from complex partial seizures requires the localization of the epileptogenic zone for surgical resection. Currently, clinicians utilize electroencephalography (EEG), psychological tests, and various neuroimaging modalities together to determine the location of this zone. We investigate the use of positron emission tomography (PET), magnetic resonance imaging (MRI), and magnetic resonance spectroscopy (MRS) in the presurgical workup and analysis of patients with complex partial seizures. The results of imaging studies of 25 patients are compared for lateralization accuracy and relative concordance. !14
