Computed tomography (CT scan)

Cardiovascular System Tests: CT Scan

Computed tomography (CT scan for short) provides computer-generated images of the heart, brain, and other areas of interest. Some specialized types of CT scans can also be used to diagnose early atherosclerosis in the heart before symptoms appear. These include:

Electron beam computed tomography (EBCT)
Multidetector computed tomography (MDCT).

Both of these tests can identify and measure calcium buildup in and around the coronary arteries. If you are at high risk for heart disease, your healthcare provider may suggest one of these tests even if you have no symptoms.
