Coronary Calcium Screening

How does Calcium Scoring work and what does the procedure involve?

A high-speed, sub-second CT scanner called the Light Speed Plus CT is used to obtain numerous images of the coronary arteries. The images are obtained in synchronization with the heartbeat using an EKG monitoring device. The images are analyzed by a board-certified radiologist using a sophisticated software program. The examination is painless, safe and quick. There are no needles and, in most instances, no need to remove clothing. The scan takes only 25 seconds but, including preparation, the total time spent is 10-15 minutes. The radiation dose is comparable to having a chest X-ray study.

What will Calcium Scoring tell me and my doctor?

The test is designed to detect calcified plaques in coronary arteries. This can be an early warning sign of significant heart disease. Based upon the findings, your doctor can determine the need for lifestyle modifications, treatment or further testing. It should be kept in mind that this study is for screening risk assessment only and does not show actual blood flow. It is not, nor is it intended to be, used for assessing the status of patients with known coronary-artery disease who have had bypass surgery, angioplasty or stenting procedures. It is not a substitute for comprehensive evaluation by your physician. Physician referral is not required. Appointments can be made by calling the St. John Macomb Hospital Central Scheduling Office at 586-573-5160.
