This chest X ray shows
calcified coronary arteries.
The lateral view is often best for demonstrating calcium in the coronary vessels. Calcifications are much more common in the proximal parts of the vessel, usually within two centimeters of the root of the aorta and reflect coronary atherosclerosis.
In this enlargement of the lateral view, the
railroad track shadows of calcium are more easily seen. There is proximal calcification of some of the branches of the main vessel.
