Abstract
The advantages of magnetoencephalography (MEG) in the field of epilepsy are numerous; just like electroencephalography (EEG), MEG is able to noninvasively measure epilepsy-specific information (i. e., the brain activity) independent of blood flow with a very high temporal resolution in the order of milliseconds. Thanks to its unique sensitivity to tangential sources, it gives the full picture when combined with EEG. It allows for accurate source imaging and shows a high sensitivity for neocortical sources. In this article, the technique and its clinical impact are reviewed.
