Coronary CT Angiography

Coronary CT Angiography

The Coronary CT Angiography specialists on Long Island

A coronary CT angiogram is an imaging procedure used to obtain high resolution images of the arteries that supply blood to the heart muscle. Intravenous contrast is administered to provide a high-definition evaluation of artery patency and to rule out the potential for coronary artery disease.

Our specialized cardiac imaging team has been performing this test for decades and is always available for any questions or concerns you may have about the procedure.


What is CCTA?

A CCTA is a noninvasive test that produces detailed 3D images of the arteries in your heart to detect abnormalities in blood flow. It is used to diagnose cardiovascular disease by detecting calcium in your arteries, a sign of fatty build-up called plaque. Plaques in the arteries of your heart are the main cause of heart attacks and can block the flow of blood and the oxygen supply to your heart.


Why might a CCTA exam be performed?

You may be recommended for a CCTA if you have symptoms of cardiovascular disease or if you are diagnosed and your doctor needs more information. Reasons for a CCTA may include:

  • Abnormal test results from another test such as an echocardiogram or stress test
  • Abnormal structure of your coronary arteries
  • Risk for developing coronary artery disease
  • New or worsening coronary artery disease symptoms
  • You have undergone coronary artery bypass graft (CABG) surgery
  • Certain risks associated to elevated cholesterol levels
  • Preventative analysis due to family history of coronary artery disease

CCTA with Calcium Scoring

You may be recommended to receive a calcium scoring with your CCTA exam. This screening heart test assists in detecting calcium deposits in the coronary arteries of your heart. A higher coronary calcium-score suggests you have a higher chance of significant narrowing in the coronary arteries and a higher risk of future heart attack. Read more.
