What is coronary calcification?
Coronary calcification occurs when calcium deposits in your blood vessels. Research shows that the amount of calcification is directly related to the amount of plaque in your arteries. This plaque increases your likelihood of developing heart disease.
Why is CT scanning used to detect coronary calcification?
CT scans can detect the amount of calcium build-up in the coronary arteries. The test, otherwise known as a cardiac score, is used to help diagnose heart disease. Because heart disease is a leading cause of death, it is important to undergo screenings. CT scans are one of the most accurate ways to detect calcium build-up in your coronary arteries.
Who should have a cardiac score?
Your doctor may recommend a cardiac score if you:
- Smoke
- Have diabetes
- Have high blood pressure
- Have high cholesterol
- Have coronary artery disease
- Are overweight
- Live a sedentary lifestyle
- Experience a high level of stress
- Experience atypical chest pain
How should I prepare for my CT scan to detect coronary calcification?
To prepare for a CT scan, we recommend you dress comfortably. Also, avoid any clothing that contains metal objects such as snaps or zippers that can affect the CT image. You will not be asked to wear a gown unless the technician feels your clothing could affect the results of the scan. Depending on your individual scan, you may receive a contrast injection. Contrast material is a dye that makes your organs and blood vessels more visible when you are scanned. If contrast is used, you will be asked not to eat or drink for 4 hours prior to the procedure. After the scan you should drink plenty of liquids to help flush the contrast out of your system.
What type of equipment is used in the procedure?
The CT scanner is a specialized machine that looks like a large doughnut. You will lay on a movable table that goes in and out of the center of the machine. Most CT studies use an advanced unit called a spiral CT that records a large number of pictures in a short time.
How does a CT scan to detect coronary calcification work?
A CT scan requires that you to lie flat your back. A rotating device spins around your body creating a beam of x-rays. A detector takes snapshots of the beam after it passes through your body and a powerful computer program then processes the images and displays them in different ways for examination. The technician will communicate with you throughout the procedure, but will need to leave the room briefly to run the computer. A radiologist then reviews the images to look at the area in question. The scan will take about 5-10 minutes and the entire experience should last no more than 30 minutes.
Will I experience pain during the procedure?
No, CT scanning is a painless procedure. If contrast material is used, you may feel flushed or get a metallic taste in your mouth, usually lasting no more than a minute or two. In rare cases, you may experience other side effects. Contact the CT technologist or your doctor if these occur or if you have questions about the use of contrast.
How will I get the results from my cardiac score?
When your exam is complete, you may return to work or other normal activity immediately. Our board-certified radiologists will read your exam, and the results will be reported to your referring physician within 24 hours.
