I had an MRI a couple of months ago and was not looking forward to is as they were scanning my head which means going all the way in head first. To my surprise they had an "open" scanner which has no sides at all. It's a bit like two burger buns one above and one below you and virtually nothing else so you can see all around you. If you need another scan I'd recommend enquiring if they have an open scanner.

My only problem was I'd been running late and had just ridden up the worlds steepest hill on a bike, I was totally out of breath, covered in sweat and my heart was pounding. I then had to try to keep still while beads of sweat ran down my face and I was dying for a drink. Much fun!
