You will have a gazillion different responses abut how and MRI. I find the only real 'problem' with mine is my size. A larger body just doesn't scrunch into that tube as well as others. Have music piped in, take those little rubber scrunchy ear plugs, or they may even provide them. And remember they are always there to talk to you if you need to let them know you are having some trouble. I have never, but some people get a little ancy with it.
