Cardiac CT Scan

Cardiac CT Scan

Introduction

A cardiac CT scan is an imaging test that makes use of X-rays to take detailed pictures of your heart and the blood vessels around it. This test can help doctors check for problems with your heart and blood vessels, like blockages or calcium buildup.

Many people feel nervous about medical tests, especially ones that involve radiation. It’s normal to have questions and worries. This article will explain what a cardiac CT scan is, who can benefit from it, and what to expect during the process.

What is a Cardiac CT Scan?

A cardiac CT scan, also called a coronary CT angiogram, is a type of imaging test that provides detailed pictures of your heart and blood vessels that supply it with blood. It is often used to check for heart disease, blockages in the arteries, or other problems.

During the test, you lie on a table which slides into a large, doughnut-shaped machine known as a CT scanner. The scanner takes X-ray pictures from many angles around your body. A computer puts these pictures together to create detailed images of heart and blood vessels.

When Would You Need a Cardiac CT Scan?

A cardiac CT scan can give your doctor/healthcare provider more detailed information than other imaging tests. Here are some reasons why your doctor might recommend a cardiac CT scan:

• Evaluate chest pain or shortness of breath: To determine the underlying cause.
• Check for heart artery issues: To assess calcium buildup, plaque, narrowing, or blockages.
• Assess heart valves: To identify any abnormalities or problems.
• Examine the aorta: To detect aneurysms, dissections, or other issues.
• Plan for heart surgery: To help determine the best approach, whether open, minimally invasive, or robotic.
• Plan for valve procedures: To assist in planning transcatheter or percutaneous valve procedures.
• Plan for arrhythmia ablation procedures: To evaluate the heart’s electrical activity.
• Assess for complications: To monitor for potential complications after heart procedures.
• Identify congenital heart problems: To detect birth defects or abnormalities.
• Examine tumors or masses: To identify and characterize any growths in or around the heart.
• Evaluate the pericardium: To assess for fluid or calcification around the heart.

Who Needs a Cardiac CT Scan?

A cardiac CT scan may be recommended if you:

• Have symptoms of heart disease, such as chest pain or shortness of breath
• Have a family history of heart disease
• Have risk factors for heart disease, like high cholesterol, high blood pressure, or diabetes
• Had an abnormal result on another heart test, like an EKG or stress test

However, some people may not be good candidates for a cardiac CT scan, such as those who are pregnant or have severe kidney disease.

Why is the Procedure Conducted?

A cardiac CT scan is done to check for signs of heart disease and to help guide treatment. It can show if there is:

• Buildup of calcium/plaque in the arteries of your heart (coronary artery calcium score)
• Narrowing or blockage in the arteries (coronary artery disease)
• Damage to your heart muscle from a heart attack
• Problems with the structure of your heart

By identifying these issues early, doctors can work with you to manage your heart health and prevent complications.

What to Expect?

Before your cardiac CT scan, you may need to:

• Avoid eating or drinking for a few hours before the test
• Take off any jewellery or metal objects
• Change into a hospital gown
• Have an IV placed in your arm to inject the contrast dye

Your doctor will also discuss your medical history and any medications you are taking. You will also need to check kidney function before the test is done.

During the cardiac CT scan:

• You will lie down on a table which slides into the CT scanner machine
• The scanner will take X-ray pictures from many angles around your body
• You may be asked to hold your breath for a short time during the scan
• If contrast dye is used, it will be injected through the IV in your arm
• The entire scan usually takes about 10-30 minutes

After your cardiac CT scan:

• You can usually go back to your normal activities right away
• If contrast dye was used, you should consume plenty of fluids to help flush it out of your body
• Your doctor will evaluate the images and discuss results with you

Risks or Complications

Cardiac CT scans are generally safe, but there are a few potential risks:

• Allergic reaction to the contrast dye (rare)
• Kidney damage from the contrast dye (more common in people with kidney problems)
• Radiation exposure (the amount is small, but it’s important to limit radiation when possible)

Talk to your doctor about any concerns you have about the risks.

Conclusion

A cardiac CT scan is a valuable tool for checking the health of your heart and blood vessels. By understanding the test, its benefits, and what to expect, you can feel more prepared and less anxious about the process. If you think you may need this test, talk to your doctor to discuss your options and get personalized recommendations for your heart health.

Frequently Asked Questions (FAQs)

1. How much radiation is used in a cardiac CT scan?

The amount of radiation used in a cardiac CT scan is small, but it’s still important to limit radiation exposure when possible. Talk to your doctor about the risks as well as benefits for your specific situation.

2. Do I need to take any special precautions after the test?

If contrast dye is used, you should consume plenty of fluids to help flush it out of your body. Other than this, you can generally go back to your normal activities right away.

3. How long does it take to get the results of a cardiac CT scan?

Your doctor will evaluate the images from your cardiac CT scan and discuss the results with you, usually within a few days. The exact timeline may vary.

4. What is the difference between a cardiac CT scan and a cardiac catheterization?

A cardiac CT scan is a non-invasive imaging test that makes use of X-rays to take pictures of the heart. A cardiac catheterization is an invasive procedure in which a thin tube is inserted into your heart to check for blockages or other problems.
