Chow, if you got the means to do it, then do it. I`m sure you have done the research on the responsibilities of a MRI tech, and you find it interesting.
If you are in a dead end job, then there is no reason why you can`t explore your options to do something that you half-way enjoy. I realize jobs are not usually "happy fun time" but it helps when you don`t mind getting up and going to work everyday.
A bonus for you is that you do not have any kids, so you could spend the time focusing on your new career.
Good luck!
