You’re absolutely right, they’re not interchangeable. MRIs are better suited for soft tissues.

If you’re looking for a broken bone, take a single x-ray image instead of a whole CT scan, which is a far higher dose of X-ray radiation.

Largely agree, but still very much depends on what you're screening for. For example, my oncologist still recommends CT over MRI for post-surgical screening as the increased resolution makes it possible to detect tumors a bit earlier.

		I’m not familiar with the parameters of the machines readily available to your provider, but I can say that the risk/reward scenario for an intervention for someone coming out of cancer surgery is distinct. We give cancer patients chemo and radiation that we would never give to someone who just showed up in the ER or was still undergoing preliminary diagnostics.
