What is a calcium score CT scan and what does it diagnose?
A calcium scoring computed tomography (CT) scan uses imaging technology to look for calcium OR plaque on coronary artery walls. Because calcium in the coronary arteries may be a sign of coronary artery disease (CAD), this test can help in early detection of heart disease.
A calcium score CT scan requires an order from your doctor and is by appointment only. The test may benefit men over 40 and women over 50 who are at medium risk of developing heart disease.
What to Expect
A calcium score CT scan is painless and takes about 30 minutes. Before your test you will be asked to:
- Put on a hospital gown
- Remove all metal objects that might interfere with the scan
- Lie flat on the table connected to the CT scanner
You also will be connected to an EKG machine to measure your heart’s electrical activity.
During the Exam
During the test, you may be asked to hold your breath for 20 to 30 seconds while the CT scanner takes pictures of your heart.
Test Results
After your test you will receive your calcium score result from your doctor.
If your score is high, your doctor will discuss options to help lower your risk of developing heart disease, such as medicine or lifestyle changes.
