The MRI magnet isn't as critical as you might think. Higher magnets tend to make for more signal faster. 3 Tesla magnets seem to be the big thing now. The problem is that many places compensate for the increased signal by speeding up the scans; the final result isn't any better than what's produced by a smaller magnet. The best thing to do is to make sure the doc who orders the MRI specifies what he/she needs to see and that you go somewhere where they'll work to make sure their images support that need.
