Applications

Wearable MEG opens new domains for biomagnetic sensing in research and in medicine while expanding the scope of existing MEG applications.

Epilepsy

Supporting surgical decisions in patients with drug-resistant intractable epilepsy

people worldwide have epilepsy

have seizures that cannot be controlled with medicine

increased risk of death for people with epilepsy with uncontrolled seizures

MEG can improve finding the location within the brain responsible for causing the epileptic seizures.
MEG can help when an MRI lesion is found and EEG findings do not agree. MEG sometimes confirms the epileptic activity is coming from the lesion.
MEG can be used in patients who have had past brain surgery. EEG measurements may be altered due to the changes in brain anatomy as a result of surgery.
MEG can also be used to help decide the best placement of intracranial EEG and can sometimes allow clinicians to avoid intracranial EEG and proceed directly to surgery.

Wearable MEG is demonstrating potential to monitor activity during seizures. This may further help doctors find the cause of the seizures.

Comprehensive mapping of normal brain function such as language for planning brain surgeries

people worldwide need brain surgery each year

Brain surgeries worldwide in a year

for patients with drug-resistant epilepsy need assessment of language in each hemisphere of the brain before surgery.

MEG is used for surgeries involving brain tumors, other lesions, brain abnormalities, arteriovenous malformations, and previous brain surgeries.
MEG is used to plan brain surgeries to minimize the loss of normal brain function.

Inclusion of difficult to measure populations

Wearable MEG will allow testing in a wider range of patients who cannot tolerate holding still eliminating the need for anesthesia for these patients.
