Ok I have only read some of this thread but FWIW two years ago I underwent some back surgery and had a few MRIs. I was able to record one of them on a small handheld mini cassette which the technician graciously allowed to sit on his desk outside the actual room of the MRI. He DID look at me rather funny when I asked him if I could record the sounds but after a brief discussion he agreed. I suppose they see weirder folks. So, the point is if you don't ask you can't get it. I have been working with the source material I got for some time now and I have to agree with all the comments of how it is rhythmical, ambient, industrial, etc. In my experience in environmental sound there is nothing quite like it. FWIW I am only familiar with the enclosed MRIs. there are not "open" MRIs which I would imagine sound quite different.
