I'm miserable at my job and am looking to make a change. The medical field is supposed to be growing. Xray/mri technician looks very interesting to me. I was wondering where do you go to learn this profession? Is it a college course, trade school? Also how long is school and what kind of classes are necessary? Is is a union job, how are the benefit and pay? Any information would be great. I gotta get out of where I am now.
