Cardiac CT Angiography

Cardiac CT Angiography (CTA) is a revolutionary way to non-invasively visualize the inside of the coronary arteries in just seconds. That means easier, painless diagnosis of the cause of symptoms and earlier detection of developing vascular disease long before symptoms have started.


Cardiac CT Angiography is a highly accurate alternative to Cardiac Catheterization for those people who have an abnormal stress test or have had chest pain. Cardiac CT Angiography can quickly and non-invasively determine whether significant coronary artery disease is present.

Cardiac CT Angiography can accurately exclude the presence of significant blockage in the coronary arteries. Nearly one out of every three people advised to have a Cardiac Catheterization ultimately find they do not have any have significantly blocked arteries. Cardiac CT Angiography can be an excellent way to avoid the risk of complications and eliminate the need for a stay in the hospital.

If you have an elevated Coronary Calcium Score, a Cardiac CT Angiography can be used to determine the severity of any narrowing that may be present in the coronary arteries.

 Cardiac CT Angiography vs Cardiac Catheterization

In the past, Cardiac Catheterization has been the most important tool for evaluating the arteries of the heart. But Cardiac Catheterization is an invasive procedure that requires an incision in the groin, inserting a catheter into an artery in the leg and advancing the catheter under X-ray guidance to the heart. Contrast dye is then injected directly into the arteries on the surface of the heart and X-rays are taken that show whether any of the vessels are narrowed.

Cardiac CT Angiography requires only a small IV in the arm. A small amount of dye is injected into the vein followed by a 10-second CT scan of the heart.

Unlike a Catheterization, with Cardiac CT Angiography, there is no risk of vascular damage, heart attack or stroke. After the scan, the IV is removed and you can go home, to work or resume your normal activities immediately.

 The Princeton Longevity Advantage

The Princeton Longevity Center is the region's leader in Cardiac CT Angiography. We do more Cardiac CT Angiographies in a day than most centers do in a month. That means our highly experienced staff and technicians know how to make the experience as easy as possible for you while getting the most reliable results.

Our Director of Cardiac Imaging, Dr. John Rumberger, is a world-renowned pioneer in the field of Cardiac CT Angiography and did much of the original research in the field as a professor at the Mayo Clinic. Cardiologists and Radiologists from all over the world come to Princeton Longevity for our highly acclaimed Cardiac CT Training Course to learn how to perform and interpret Cardiac CT Angiography.

The Princeton Longevity Cardiac CT Angiography physicians meet ACCF/AHA Level 3 criteria, the highest level of expertise recognized for Cardiac CT. Our Medical Director, Dr. David Fein, is one of the first physicians in the country to be Board-Certified in Cardiac CT. That means you can be confident that your scan is read and interpreted by leading experts in the field.

 Ultra Low-Dose Cardiac CT Angiography

The Princeton Longevity Center uses the latest in radiation dose reduction techniques. In many cases, our Low Dose CT Angiographies can be done with a fraction of the radiation of the "usual" radiation exposure and with far less radiation than a stress test or cardiac catheterization.
