N2 - Epilepsy is a common neurological disease that affects about 50 million people worldwide. Extratemporal lobe epilepsy, which represents an important type of epilepsy, may involve seizure activity in various lobes and the surgical treatment in these patients tends to have less favorable surgical outcome. Noninvasive seizure imaging in drug-resistant patients is of vital importance to image the seizure onset zones (SOZs) and understand the mechanisms for an improved treatment plan. In this study, we directly imaged the seizure sources in 8 extratemporal lobe partial epilepsy patients from noninvasive EEG. The surgically resected regions and SOZs identified from intracranial EEG (iEEG) recordings were used to evaluate the source imaging results. All of the eight patients underwent resective surgery and the estimated seizure sources were co-located with the resection zone. Seven of the patients had iEEG recordings available and the source imaging results were concordant with the SOZs marked on the intracranial recording grid. The present results suggest that dynamic seizure imaging could be potentially useful to image the SOZs of extratemporal lobe seizures and help the pre-surgical planning of epilepsy patients.
