I had an MRI on my back about 4 years ago. It's not that bad. I mean it is because you can't move and in you're in a small space but normally the technicians will play music and talk to you to try and keep you calm. They also gave me dye in an IV, of course my luck I got a newbie and she injected it in the wrong spot so 1/2 through the IV they had to take me out reinject me than put me back in. I was terrified, even people who aren't clausterphobic panic, it will be ok though but I suggest bringing someone for support when you go in. My panic got so bad I could barely drive and I was seeing things everywhere (schizo or DID not sure which caused that) so bring someone with you in case you can't drive as well... Good luck!!!
