Ive had a couple of mri's, one on my knee and one of my head, and all theyve ever done is open like some back door with no lights on so i had no idea where i was or if i was in a confined space. I think they asked me beforehand if i was claustrophobic and pretty sure i answered yes. I swear one time i thought they were shoving me out to the alley, thats how sketchy the door looked. But they fooled me!
