What Kind Of Person Should Study For Mri/cat Scan And X-ray Tech?

I am currently 30 years of age and intend on attending college this spring. I currently work at a warehouse. I wanna go to college to get a better paying job but also to do something I might enjoy. So wanted opinions from people who currently involve themselves in this career field. I was told I would need to go attend a 2 year x-ray tech program than a year for MRI/Cat Scan then I could pratically do anything in that field.
Keep in mind I have no prior knowledge of human anatomy or physiology. I am also an individual who enjoys history but feels maybe studying to a be a history professor could be impratical givin my age and current income. Although will need federal assitance in order to attend any college. Thank you
