SHOULD I DO BOTH MRI and CT?

Hey I was thinking to be a radiology tech certified in both MRI and CT. I got a pre-med degree, but after doing some research, I believe it is a solid career change. I was planning to work in Boston, Massachusetts soon and wondering whether I should be certified for both MRI and CT to make the most money there. So my question is do i have certified in both CT and MRI to make the projected 6 figs? how is the career in terms of Work/life balance. and honestly How hard is it as a career?
