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 new 64-slice CT
scanners enable more
accurate diagnoses of
aortic dissections and
pulmonary embolisms, by
resolution and speed"
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
After the scan, the IV is
removed and you can go home, to
work, or resume your normal
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
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
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.
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.
