Question

Does a chest x-ray or a spine x-ray show clogged arteries or a bad heart?

Answer 1

X-ray cannot detect clogged arteries but it can detect Cardiomegaly (enlargement of the heart)

Explanation:

Arteries are too deep to be seen in an x-ray. It would require more sophisticated testing like 3D Echo cardiogram while Cardiomegaly can be detected easily because the heart appears alongside the lungs with the x-ray usually in the apicolordotic view.
