Can I get an MRI for a cardiac calcium score rather than a CT?

I tried to research it by googling, but I’m confused.

I’m going to call the diagnostic center on Monday, but I’d like to know before I call. I remember seeing an interview where a researcher talked about using MRI on women for cardiac scans to protect their breast from being radiated. I don’t know if it included a calcium score scan or something else. Maybe the something else is just as good.

I also would want to know if the MRI involves contrast, I know the CT doesn’t.

I really prefer not to get the radiation if possible. I looked it up and it says 3–8 years background radiation.
