My MRI center will let me bring my own music CD to listen to while "shooting the tube". Helps to have music I know rather than a radio station.

I request a cloth to cover my eyes. As long as they are closed, I don't freak as much. The times that they've had to stop the scans because of panic was the times my eyes accidentally opened while I was in there.

I breathe deep and pray. I know that everything's going to be ok from the number of times I've been in there. Still, an irrational fear is just that - Irrational. I just do what I can.
