A MEG (magnetoencephalography) scan is a brain image done to measure the electrical activity of the brain. This test will show which areas of the brain are firing abnormally, or “spiking.” It provides different information than a scalp EEG. During the exam, you will be asked to sit or lay quietly in the open scanner.

Facilities that perform this type of imaging are limited. Talk to your physician for a recommendation.

How to prepare for a MEG

On the day of the procedure, take all medications as prescribed by your physician. There are no restrictions on what you can eat or drink prior to the exam.
