At Children’s Hospital of Pittsburgh of UPMC, we believe parents and guardians can contribute to the success of this procedure, and we invite you to participate. Please read the following information to learn about the procedure and how you can help.
Magnetoencephalography (mag-NET-oh-en-seph-uh-LOG-gruff-ee), or MEG, is a test that uses sensors to form an image of magnetic fields produced within the brain. Doctors use these images to pinpoint areas of brain activity that indicate epilepsy. MEG is one of several tests that your child’s doctor may order to see if surgery is an option to control your child’s epilepsy.
When MEG is used with MRI, a test that shows the brain’s structure, the combination of images can show precisely which areas of the brain may be causing the seizures and which areas are working normally.
MEG is completely noninvasive, meaning that all testing is done on the outside of the body, and it does not hurt. No shots or needles are used, and there is no exposure to radioactivity or
x-rays. It is similar to electroencephalograpy (EEG) and uses the same type of electrodes on the scalp as EEG and Video EEG testing. There is no risk involved with the MEG.
Before your child’s MEG scan:
The MEG scan itself takes about 1 hour, but getting set up for the test can take up to 2 hours. The length of your appointment may vary. Here is what to expect:
When the EEG electrodes and MEG coils are in place and the quality of the signal has been checked, the test is ready to begin. Because the MEG machine is very sensitive and will pick up the electrical brain activity of everyone in room, your child must be in the room alone; parents will be shown to the waiting room.
The most important role of a parent or guardian is to keep your child calm. The best way to keep your child calm is to be calm yourself. Knowing what to expect and explaining it to your child beforehand is the best way for both you and your child to be prepared for this procedure.
If your child has any special needs or health issues you feel the doctor needs to know about, please call the Division of Child Neurology before the procedure and ask to speak with a nurse. It is important to notify us in advance about any special needs your child might have.
