A computed tomography (CT) scan of the heart is an imaging method that uses x-rays to create detailed pictures of the heart and its blood vessels.

  • This test is called a coronary calcium scan when it is done to see if you have a buildup of calcium in your arteries.
  • It is called CT angiography if it is done to look at the arteries that bring blood to your heart. This test evaluates if there is narrowing or a blockage in those arteries.
  • The test is sometimes done in combination with scans of the aorta or pulmonary arteries to look for problems with those structures.
CT scan

CT stands for computerized tomography. In this procedure, a thin X-ray beam is rotated around the area of the body to be visualized. Using very complicated mathematical processes called algorithms, the computer is able to generate a 3-D image of a section through the body. CT scans are very detailed and provide excellent information for the physician.
