Electron-beam computed tomography (EBCT) is a fast and sensitive test for detecting calcium build-up in the arteries of the heart. It uses an electron gun instead of regular x-rays to scan the chest.

The amount of calcium build-up in the arteries will give your doctor an idea of whether a condition known as atherosclerosis has developed. This condition can lead to narrowing of the arteries, heart attack, stroke, and other serious conditions.

EBCT may be used to screen people for coronary heart disease (CHD). It can be used before or after symptoms actually appear. This test may be most useful for people at moderate risk for heart attacks. This is important because, for many people, the first sign of CHD is a heart attack.
