Magnetoencephalography: at the forefront of optimizing epilepsy surgery
Approximately 50 million people are affected by epilepsy worldwide [1]. About 30% of these patients are expected to develop drug-resistant epilepsy (DRE) and are a potential candidate for epilepsy surgery work up. Therefore professional organizations and clinical guidelines recommend that patients with DRE discuss or undergo evaluation at a comprehensive epilepsy center for consideration of epilepsy surgery or other specialized services [2].
Magnetoencephalography (MEG) scan offers a non invasive technology for presurgical evaluation of patients with DRE. Utilizing MEG also provides the potential to achieve better outcomes for patients by localizing seizure onset and allowing for more precise pre-surgical evaluations. Despite its demonstrated success in seizure localization and being approved for the presurgical evaluation of refractory epilepsy, MEG continues to be overlooked by epilepsy and neurosurgical communities [3].
