64-Slice CT technology revolutionizes heart attack prevention

Cardiac CT Angiography (CTA) is a new and revolutionary way to non-invasively visualize the inside of the coronary arteries.  With the latest advances in high resolution scanning, the SiemensDefinition 64-Slice CT Scanner can create amazingly detailed and accurate images of the heart, lungs, and arteries in just seconds.  That means easier, painless diagnosis of the cause of symptoms and earlier detection of developing problems before symptoms have started.

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 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.

The Princeton Longevity Center is accredited by the American College of Radiology. This means you can rest assured that Princeton Longevity meets the highest standards for ensuring your scan is the highest quality.

Ultra- Low Dose 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.

CT Angiography vs Cardiac Catheterization:

Until now, 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 vein of the arm. A small amount of dye is injected into the vein followed by a 10 second CT scan of the heart.

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.

Avoiding Invasive Tests with Cardiac CT Angiography:

Cardiac CT Angiography can accurately exclude the presence of significant blockage in the coronary arteries. Nearly 1 out of every 3 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. 

Cardiac CT Angiography is a highly accurate alternative to Cardiac Catheterization for those people who have an abnormal stress test but are unlikely to have significant heart disease. In people with non-diagnostic (equivocal or borderline) stress tests, or those with “negative” stress tests but who are at high risk of coronary artery disease, Cardiac CT Angiography can quickly and non-invasively determine whether significant coronary artery disease is present.  If you have an elevated Coronary Calcium Score, a Cardiac CT Angiography can be used to determine the severity of narrowing of the arteries.

Insurance Coverage:

Cardiac CT Angiography is covered by Medicare and by many private health plans. The CPT Code for Cardiac CT Angiography is 75574.

Cardiac CT Angiography and radiation:

A typical Cardiac CT Angiography at the Princeton Longevity Center will expose patients to about less than 6 mSv of radiation. Depending on factors such as heart rate, body size and the reason the scan has been ordered, we are often able to keep the radiation dose for a CT Angiography less than 1 mSv.

As a basis for comparison, a Nuclear Stress Test is typically 12-25 mSv of radiation exposure. A Cardiac Catheterization is generally 6-12 mSv. While it is important to minimize unnecessary radiation exposure as much as possible, a Cardiac CT Angiography is usually the test with the lowest radiation dose that will allow us to determine if there is a blockage in a coronary artery.

According to the US Nuclear Regulatory Commission, 1 mSv of radiation exposure may increase your lifetime cancer risk by about 1 in 25,000. Put another way, the cancer risk increases from 20.000% to just 20.004%. On the other hand, your risk of dying from cardiovascular disease that goes undetected and untreated is 36%. We believe that the potential benefit of early detection of cardiovascular or other diseases more than offsets the extremely small potential risk of this level of radiation exposure.
