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.
