:: CTA - CT Angiogram
Coronary artery disease is the No. 1 killer of men and women in America
Viewing Arteries in a Whole New Way
In the past, the recognized gold standard
for detecting atherosclerotic plaque was the
use of coronary angiography and
intravascular ultrasound.
Today, however, the American Heart
Association considers CT scanning to be one
of the most effective, non-invasive methods
for the detection of calcification in the
coronary arteries.
CT Angiography (CTA) uses x-rays to visualize blood flow in arterial vessels throughout the body – from arteries serving the brain to those bringing blood to the lungs, kidneys, arms and legs. Compared to catheter angiography, which involves injecting contrast material into an artery, CTA is much less invasive and more patient-friendly. It can be far more cost-effective than conventional coronary angiography. |

CTA is commonly used to:
- Examine the pulmonary arteries in the lungs to rule out pulmonary embolism
- Detect thrombosis (clots) in veins
- Visualize blood flow in the renal arteries (those supplying the kidneys) in patients with high blood pressure and those suspected of having kidney disorders.
- Identify dissection in the aorta or its major branches.
- Identify aneurysms in the aorta or in other major blood vessels.
- Identify an aneurysm or arteriovenous malformation inside the brain.
- Discover atherosclerotic disease in the legs.
- Detect narrowing or obstruction of arteries in the pelvis and in the carotid arteries, which bring blood from the heart to the brain.
- Map the details of arteries feeding certain tumors.
CT-Angiography of the coronary vessels
|
This detailed examination is performed by injecting a contrast medium (to enhance the display of the patient's anatomical cavities and vessels) in a brachial vein. ECG electrodes are positioned on the patient's chest in order to synchronize the scanner exactly to his/her heart rate. This makes it possible to acquire a complete 3D scan of the heart - a "virtual trip through the heart" - without a catheter. And this examination takes only 20 seconds. The precise results of this examination provide the doctor with information about the condition of the patient's coronary vessels. |
Your Results
Afterwards, a powerful computer reconstructs
a series of 3D, semi-transparent images that a
physician can view from any angle. Once the
images are reconstructed, our specially trained
radiologist will interpret the test.
You and your personal physician will receive
a detailed written report of the findings and any
action recommended. You will also receive a
CD-ROM containing all of your images for future
reference.
Who Should Consider
a CT Angiography?
Any individual with a family history of heart
disease or an elevated calcified plaque score
from a heart scan should consider CT
Angiography.
In addition, current or former smokers, post
bypass patients and those who suffer from
high blood pressure, high cholesterol, obesity,
post obesity or diabetes should consider the
procedure.
