Magnetoencephalography (MEG)

Magnetoencephalography (MEG) non-invasively measures magnetic fields created by the brain’s electrical activity. Clinical application began at SickKids in August 2000. It is used primarily to map epileptogenic foci and eloquent brain function. To ensure that the data is linked with structure, Magnetic Resonance Imaging (MRI) is completed as part of a MEG study.

Children with epilepsy are the primary patient group benefiting from this technology at present. MEG is utilized to determine surgical candidacy for patients that have refractory seizures. In addition, MEG also provides information used for surgical planning in neurosurgery patients with conditions other than epilepsy.

All clinical cases must be approved through the Neuro-Physiology department prior to booking. At present only orders from Neurology or Neurosurgery are accepted.
