What is Electron-Beam Computed Tomography?

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 (hardening of the arteries) has developed. This condition can lead to narrowing of the arteries, heart attack , stroke , and other serious conditions.

EBCT is useful for screening people for coronary heart disease (CHD). It can be used before or after symptoms (such as chest pain) actually appear. This is important because, for many people, the first sign of CHD is a heart attack.

It can be used to:

  • Determine the risk of CHD in people with no symptoms
  • Determine likelihood of CHD in people with abnormal chest pain
