Can magnetoencephalography guide epilepsy surgery?


  • Magnetoencephalography (MEG) was useful in deciding surgery location for patients with drug-resistant epilepsy and indicated probability of seizure freedom after resection.

Why this matters

  • MEG is an imaging technique that directly measures neuronal electrical activity and provides both temporal and spatial information.

  • Research on whether MEG provides an additional advantage over other imaging techniques for guiding epilepsy surgery decisions is limited.
