Even in a healthy person, chest xrays should be done every couple of years. Particularly if you've been having any chest pain, shortness of breath, etc. Just to make sure nothing is missed.
I believe you are taking prednisone? Bone scans are regularly done, every year or 2 years, to make sure the bones are holding up - with prednisone, our calcium is depleted and needs to be replaced and/or monitored.
These are fairly routine tests, taken as baselines and for precautions, not indicators that the Dr thinks something is going on. Nothing to worry about
