Coronary
Calcium Scoring
What is Coronary Calcium Scoring?
A cardiac CT scan for coronary calcium is a pain-free, non-invasive and inexpensive procedure that provides information about the presence, location, and extent of calcified plaque in the coronary arteries – the vessels that supply blood to the heart wall. Plaque is the build-up of fat and other substances, including calcium. Over time, they can narrow the arteries or even close off blood flow to the heart. The result may lead to painful angina or a heart attack.
The amount of calcified plaque detected on a Cardiac CT scan is used to establish your calcium score. The score, based on age, gender and other risk factors, is a strong indicator of your risk of Coronary Artery Disease In general, a high score indicates a greater plaque load and an increased risk of a heart attack. Early detection is key.

How is the CT calcium score performed?
You will be asked to lie on your back on the CT exam table for approximately 10 minutes. ECG leads are attached to your chest in order for the scanner to record the electrical activities of your heart. You are then asked to hold your breath while the images are recorded. You may resume normal activities following your exam. One of our radiologists that are specially trained to supervise and interpret the radiology exams, will review the images and send a report to you, and to your referring doctor.
