The only clinical MEG in Minnesota

February 17, 2012 · by Minnesota Epilepsy Group · Technology



Did you know that Minnesota Epilepsy Group has the only clinical MEG machine (Magnetoencephalogram) in the state of Minnesota?  As a level 4 epilepsy center we offer a comprehensive package of diagnostic services and expertise no other center can provide.




MEG seizure focus on MRI

uses superconductive sensors to map the magnetic fields created by the brain’s electrical activity.  For people with seizures it can pinpoint where the seizures are coming from.  Those seizure areas can be plotted onto a picture of your brain from an MRI.

MEG can also map the location of brain functions including motor, sensory and primary language areas.  This kind of mapping is especially important when removing brain tumors and can provide your neurosurgeon vital information on locations of vital function.

  1. That machine looks to be far less terrifying than the MRI machines I’ve been shoved into. Claustrophobia is a big problem for me with MRIs, although the open sided MRIs are not quite so bad, being strapped down for the test still causes it to flair.

    But I do wonder if it just a coincidence that the MEG (Magnetoencephalogram) machine is at the MEG (Minnesota Epilepsy Group)?

    I’m a stress seizure person too.

  3. I know someone whose seizures are triggered by exposure to electromagnetic fields, especially from cell phones, wifi, and cell towers. I am wondering how the emf created by the machine itself might interfere with the brain function of the person under study. Is it really possible to get an accurate picture of brain function outside of someone’s normal environment? If it is true that radiofrequency radiation can cause depolarisation of neurons, what kind of dosimetry is being down in and around the MRI machine? How do technicians/doctors compensate for this?
