I suspect the term “regional bones” is a mistake. Visualizable bones may have been the original meaning.
Hyperaeration, or hyperinflation of the lungs means air is trapped in the small airways so the lungs appear larger than usual on the chest x-ray. This simply means that you were breathing hard when the chest x-ray was taken. In the short term, it really does not mean anything serious. This is a very common finding when asthma is poorly controlled, like during an asthma attack. This same finding is seen in the lungs of chronic smokers. It can also be due to a virus.
This all sounds very normal.
