Coronary Artery Calcification Scoring

What is Coronary Artery Calcification Scoring?
Coronary Artery Calcification Scoring in a non-invasive method for identifying the presence of plaque before coronary artery obstruction occurs. The exam is performed using a CT scanner. It is generally recommended for men 45 and older and women 55 and over who are at risk for Coronary Artery Disease but who have no perceived symptoms.

How should I prepare for the procedure?
Please wear loose, comfortable clothing. You may be asked to wear a gown during the exam. Any metal objects must be removed before the exam. No special preparations are necessary for the exam.

What will I experience during the procedure?
You will be positioned on a CT table, usually lying flat on your back. Electrodes are attached to your chest and an Electrocardiograph (ECG) machine that will record your heart activity. The table will be moved through the scanner during the procedure. You will be alone in the room during the exam, but will be able to talk to your technologist at all times. The exam usually takes only 15 minutes.

Who interprets the Coronary Artery Calcification Scoring?
A board certified radiologist will analyze the images and send a signed report to your primary care or referring physician, who will share the results with you. A negative test means no calcification within the coronary arteries was present and chances of developing Coronary Artery Disease within the next two to five years are extremely low. A positive test means calcifications were found. The score itself can help determine the possibility of myocardial infarction over the next few years.
