That didn't go well......
I had a cough when I did my first MRI - they told me about 40 minutes into a 45 minute session that if I coughed one more time I'd have to come back later and start over...longest 5 minutes of my life!
Was it an 'open' or 'closed' MRI? The open MRI machines are a lot easier to handle if it's claustrophobia
The first time I had one, it was a closed machine...they explained the noises, etc., but just as I was getting rolled into the tube, they handed me the panic button...why would someone need a panic button, I began to wonder? I was fine until there was a 'ring out whenever you can't take it' option...then my mind wandered, and, for some reason, the movie "Phantasm" popped into my head...
Once that happened, I flicked the panic switch away so I couldn't reach it anymore... ;-)
