My friend also had MS and had a small boy way back. She swore she liked MRI's, it was alone time for her. Bring a CD you like, MRI does make banging noises but lie still and think "it can only last so long and then it's over and I won't have to do it again". Be sure to have thoughts you will use the time to think. You'll do great!! It's not so bad, just time consuming.
