Advanced Imaging in Epilepsy: How MEG Can Assist in Surgery
In the United States alone, approximately 4,000 surgeries are performed for epilepsy each year. In comparison, the estimated pool of patients who need or would benefit from surgery is 100,000-200,000 patients [1]. This significant gap in the number of surgeries actually performed could be filled largely by procedures that are non-invasive and can easily identify those that are candidates for surgery. Magnetoencephalography (MEG) is the newest, most advanced technique that can help close this gap by pinpointing the source of abnormal brain activity and seizure activity [2]. MEG is painless, safe, takes only 1.5-2 hours to perform and can help with this decision. MEG’s allow more patients to be identified for surgery, and potentially greatly reduce or eliminate their seizures.

In this webinar, viewers will learn how MEG is a key part of the epilepsy surgery evaluation, including information about the basics and safety of a MEG study as well as learning how simple and painless a MEG can be. Finally, viewers will hear about how MEG can help the surgeon by mapping key functions (speech, motor, vision) onto their MRI for use in the operating room.
