Electron-Beam Computed Tomography

(EBCT; Ultrafast CT)


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.

Reasons for Test

EBCT may be used to screen people for coronary artery disease (CAD). 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 CAD is a heart attack.

Possible Complications

An EBCT is considered a low risk procedure and uses very low amounts of radiation. Despite this, women should let their doctor know if they are pregnant.Some may also have an allergic reaction to dyes or contrast material used to enhance the images. Let your doctor know about any allergies you may have.
