Your Visit | Overview

How long is the visit?

The entire set-up and test will take approximately three hours.

How do I get my child ready?

  • Wash your child’s hair the night before the test. Do not use any oil, gel, or hairspray as that can affect the signal quality recorded with MEG.
  • Your child should take all normal medicines before the test.
  • On the day of the MEG recording, your child can eat meals but should not have any drinks or food that contain caffeine, such as soda, or chocolate.
  • Before starting the MEG recording, we can provide a change of clothes (hospital gowns) for your child if he/she is wearing metallic clothing.
  • Your child will be asked to remove, if possible, any metal objects that he/she has: glasses, jewelry, hair pins, removable dental braces, hearing aid. MEG is very sensitive to metal. Metal inside the MSR can change the results. Your child may not be able to have a scan if he/she is wearing dental braces that cannot be removed, has metal implants, a pacemaker, a stent, a shunt, and/or aneurysm clips.
  • Depending on the type of the MEG study, we may schedule a scan during your child’s natural nap time or even request to skip a nap for sleep recordings. In this case, please do not allow your child to fall asleep while commuting to the hospital.
  • If your child cannot sleep during the MEG, we will not be able to do a sleep study. In this case, we may need to schedule for another visit, if desired.

What should I bring to the MEG appointment?

It is helpful to bring something to comfort your child, such as blankets, bottles, favorite stuffed animals, or pacifiers. Please make sure there is no metal in those items, as they cannot go into the magnetically shielded room.

What should I do when I arrive at the hospital lobby?

Inside the lobby of the main building, you will see a large video screen. Once you arrive at the screen, please give us a call at 617-355-8941 and someone will come meet you.
