Contemplating on switching from U/S to MRI

Im currently an echo tech and im thinking about making the switch over to MRI. Scanning is putting a big taxation on my shoulder and it hurts to scan now. So im thinking about the longevity of my career.. I ultimately wanted to go into MRI when I did my echo schooling however inhad finished a general u/s so echo school was cut in half and thought that was the better option but down the road its not. I know its 2 completely different registries but what are the ins and outs in looking for a program. Hows a daily work schedule like. What does job security and availability look like? Is it a better work/home life balance? If anyone could share some insight. Also what to look for in programs to be able to sit for boards and stuff in that nature. Thank you
