Comprehensive Epilepsy Program
Magnetic Resonance Imaging (MRI)

MRI is a diagnostic imaging procedure that uses radio waves and magnetic fields to take three dimensional images of the brain. It can help to identify abnormal regions or lesions in the brain that may be the cause of seizures and epilepsy.

What to expect:

This test requires the child to lie very still for approximately 45 minutes. Some children may need sedation or sleep medicine to be able to complete this scan. An anesthesiologist will give your child this medicine should they need it. During the test, the MRI technologist will watch your child through a glass panel and will be able to communicate through a speaker. The MRI machine does make a loud noise, which is expected and does not cause injury. Ear plugs will be provided to lessen the noise.

It is very important that you inform us if your child has any metal objects in their body. These objects may interfere with the MRI testing process. Metal objects include a vagal nerve stimulator (VNS), Baclofen pumps, pins, or a pacemaker. If your child has a VNS the device can be turned off for the MRI and turned on after the test is complete. Please contact your neurologistís office to make arrangements for the VNS to be turned off and on if your child is scheduled for MRI.
