Heart/Cardiac

A cardiac CT scan uses advanced X-ray technology to capture detailed images of your heart and blood vessels. It's ideal for detecting coronary artery disease and assessing other heart-related conditions early.

What Is a CT Scan of the Heart?

A cardiac CT scan, or heart CT scan, is a non-invasive diagnostic procedure that uses advanced X-ray imaging to produce high-resolution images of the heart and its blood vessels. This type of scan helps doctors examine the coronary arteries, identify any narrowing or blockages, and assess a range of heart-related conditions with great accuracy.

A CT heart scan provides cross-sectional images of the heart, allowing doctors to examine the anatomy and structure in high detail. It’s particularly useful for early detection of coronary artery disease and other cardiovascular issues.

Why You Might Need a Cardiac CT Scan

You may be recommended a cardiac CT scan if you’re experiencing chest pain, shortness of breath, or have risk factors such as high blood pressure, high cholesterol, smoking, or a family history of heart disease. A cardiac CT scan can be beneficial:

• Evaluate chest pain not clearly linked to heart disease
  
• Check to see if the coronary arteries are blocked or narrowed..
  
• Evaluate the anatomy of the heart’s chambers, its valves, and the primary blood vessels connected to it.
• Monitor known heart conditions or follow-up after surgery
  

In some cases, your doctor might request a cardiac CTA (CT angiography) to get a clearer look at your arteries.

What Can a Heart CT Scan Detect?

A cardiac CT scan can identify a number of heart-related conditions, such as:

• Coronary artery disease (CAD)
  
• Calcium build-up in the coronary arteries (via a calcium score test)
  
• Aneurysms or abnormalities in the aorta
  
• Congenital heart defects
  
• Pericardial disease (issues with the lining around the heart)
  
• Tumors or infections in or around the heart
  

This makes a CT scan for heart problems a valuable tool for early diagnosis and prevention.

Do I Need a Cardiac CT Scan with Contrast?

A cardiac CT scan may be conducted either with the use of a contrast dye to enhance image clarity or without it, depending on the specific diagnostic requirements. Contrast-enhanced scans (often referred to as cardiac CTA) are typically used when your doctor needs to see blood vessels in more detail, such as in cases where blockages or aneurysms are suspected.

Contrast helps highlight arteries and veins, making it easier to spot narrowing or abnormalities. If you have kidney issues or allergies to iodine-based dyes, your radiologist will determine whether a CT heart scan without contrast is more appropriate.

How Long Does a Cardiac CT Scan Take?

A cardiac CT scan is relatively quick. The actual scan takes only about 5–10 minutes, although you should expect to spend around 30–60 minutes at the facility for preparation and post-scan instructions.

If contrast is used, you may be given beta blockers to slow your heart rate beforehand for clearer imaging. It is a painless procedure, and you may usually resume your regular activities shortly after the scan.

What to Expect During a CT Scan of the Heart

You will be placed on a motorized table that slides softly into the CT scanning equipment when you arrive for your cardiac CT scan. You may have electrodes placed on your chest to monitor your heart rhythm.

If you’re undergoing a cardiac CTA, a contrast dye will be injected into a vein in your arm. As the scanner rotates around your chest, it captures multiple images, which are then combined to create a 3D image of your heart.

The scan is quick, non-invasive, and doesn’t require any incisions. You may be asked to hold your breath briefly to avoid motion blur during the scan.

How Much Does a Cardiac CT Scan Cost?

The cost of a cardiac CT scan varies depending on your location, whether contrast is used, and the facility where it is performed. In the UK, prices typically range from £350 to £850. If you're opting for a cardiac CTA, which includes contrast, the cost may be slightly higher.

Some private clinics offer packages that include both a CT heart scan and a consultation with a cardiologist. Always confirm with your provider whether follow-up interpretations or reports are included in the quoted cost.
