I had an MRI scan yesterday so I thought I'd share my experience, as I found this thread very informative when I was told I would be having an MRI & hope I can help someone else in the same way.
I had my scan at a large NHS hospital in the north west of England. My letter said I was having "mri scan internal auditory meatus both" which, from asking a question on here, I thought would mean both with & without contrast. Initially I was very nervous & as I'm a bit claustrophobic, that aspect of the test worried me. But by yesterday I wasn't nervous at all - I considered myself lucky to get one on the overstretched NHS and knew I just had to get it done & that I could just take deep breaths to calm any claustrophobic feelings.
Anyway, I was taken through to the MRI waiting area at the time of my appointment & was given a locker to put my Ereader & phone into - they were the only items I took with me, and I was asked about jewellery/metal items. I was then left alone for 10 minutes, until the radiographer came out, very rapidly asked me all the questions I'd answered on the questionnaire, then took me into the MRI room itself. I took my shoes off, lay on the table and a wedge was put under my knees for comfort. I was given a set of ill-fitting headphones and a bulb to squeeze if I needed help. I was also offered an eye mask but refused. I asked about being given an injection but was told that I wasn't having that, the letter I had received was just a standard one. I was told it would be noisy & advised to keep my eyes shut. The whole preamble was very rapid, almost rushed, and then a cage was placed over my head & within seconds I was in the machine.
As others have already described, it's extremely noisy, I don't think the headphones helped much at all. I didn't experience any claustrophobia, and did in fact open my eyes several times which didn't bother me at all (a pleasant surprise!). Between 10-15 minutes later it was done, and they couldn't get me out of there fast enough. I was slightly dizzy when I stood up but even so the nurse was ushering me out of the room to get the next patient in.
Overall, not an unpleasant experience in itself - just the feeling of being on a conveyer belt - in more ways than one! Unfortunately several hours later my tinnitus got worse which I do suspect is connected to the noise of the scan, and that's persisted today. I'm also disappointed not to have had the contrast injection; I know that sounds odd, but I felt that would have given me a better chance of finding the answers to the cause of my dizziness & tinnitus.
