I get it bro. It's a real scary thing to have to get one. I had an MRI in December last year. It depends on the hospital but usually they give you the option to watch a movie or listen to music. I chose to watch a movie, I didn't even really notice the machine noises or register that I'm in a cramped tube basically. I'm not particularly claustrophobic though so if you are it might be a bit more noticeable. The worst part was definitely the fact that it was like 30 degrees in the room, not sure if thats just my hospital but they gave me a blanket to combat the frigid temperature. Usually if something is seriously obviously wrong they get back to you pretty quickly. Good luck!
