mag·ne·to·en·ceph·a·log·ra·phy (m g-n  t - n-sf -l g r-f)n. An imaging technique used to detect electromagnetic and metabolic shifts occurring in the brain during trauma. |
magnetoencephalography (MEG) [mag-ne″to-en-sef″ah-log´ra-fe]
a noninvasive diagnostic technique that directly measures the magnetic fields produced by electrical currents in the brain. A vaultlike device is necessary to ensure that the accuracy of the test is not affected by interference from magnetic fields produced by electrical wires and radio and television transmissions.
magnetoencephalography (MEG) (mag·nēˈ·tō·en·seˈ·f

magnetoencephalography
Biomagnetism Neuroimaging An imaging technique used to evaluate subtle fluctuations in the electrical magnetic field produced by the body; MEG measures the brain's electrical activity by evaluating the magnetic
field associated with neuronal activity. Cf Electroencephalography, PET scanning.
