One of the best MRI experiences I ever had was when the ceiling of the space I was lying inside of was painted sky blue and had clouds. They gave me a pair of earphones to wear and I got to choose the music to be played. I had soft pillows under my knees, a warmed blanket laid over me and a pleasant recorded Lady-Voice speaking to me whenever instructions were given. There was a soft breeze wafting that came from behind my head. The banging and rat-tat-tatting of the machine never bothered me. I played a fantasy in my mind that I was hiding inside a hollow tree as a child while a woodpecker tapped on the tree.
One of the worst was when I had to lie flat, no pillows, in a cold room with just a single sheet over me. They insisted I wear earplugs. It was dark inside with a little row of mild lighting on each side. The ceiling was gray. A fan blew cold air right up my nose which started up a Migraine Headache. Because they insisted I wear earplugs, the extra loud, commanding, recorded male voice telling me to hold still, even though I was frozen into place, was the most annoying of all! I had a fantasy of being the "Incredible Hulk" and wringing the neck of whoever had set it up that way. Just kidding about that part.
That first time with the music has never been repeated and I have never been able to get permission to bring in my own. So, I never ask about music anymore. If it is really cold inside, during a break in the machine noises, I will ask for the fan to be turned off, sometimes. Some people think it gets too warm and stuffy without it. But, I've never had a problem with it. During longer breaks, I do move ever so slightly to take in a very deep, slow breath and stretch a tiny bit, but never disturb the part of my body they are focusing on. The main thing about holding still is to not hold myself stiffly. That's what causes pain to arise. When I hold still, I try to think of myself as soft as butter melting in sunlight.
That is my personal philosophy about it. It may be different for others. Sometimes there are people who do not respond to this kind of treatment and remain aloof, cold, remote, sometimes arrogant, and so forth. That is their problem if they want to act that way. I am not going to let them turn me into a helpless little patient, even if they do have me in tears. I do complain to the right people if I have received unkind, inhumane or unprofessional treatment. I have been known to get up and walk out of a situation and leave them open-mouthed when I have been treated in less than a humane way.
