Magnetoencephalography recording device

Minnesota Epilepsy Group is one of only a few epilepsy programs nationally to use the Magnetoencephalography (MEG) technology for functional and seizure focus brain mapping.

This state-of-art technology aids in the pre-surgical evaluation for epilepsy and brain tumor patients.  MEG is used to identify the area of seizure onset and to map the location of brain functions.  The data from the MEG and the data from a high resolution MRI are used together to accurately locate the seizure and functional areas, this combined technology is called Magnetic Source Imaging (MSI).

The integration of this innovative technology with other diagnostic procedures by our team of skilled clinicians is another reason Minnesota Epilepsy Group is considered one of the top epilepsy programs in the nation.
