This is what I do now, I used to do CT and X-ray. MRI and CT have very little in common. While the images, very broadly speaking, look similar, the background knowledge required is very different. And they have crap interfaces. Really bad one. I save the error messages that are funniest now. MRI scanners are unreliable, temperamental, hard to get consistent results from and require constant care to avoid screwing things up! MRI isn't very good with serious trauma - too slow. I do miss that work though.
