What Is a Cardiac CT?

A Cardiac CT, or Computed Tomography of the heart, is a non-invasive scan that uses high-resolution X-rays to create 3D images of your heart. It allows clinicians to analyse the heart’s chambers, valves, and blood vessels with precision for a detailed understanding of your cardiac health.

How Is a Cardiac CT Performed?

Before a heart CT, your cardiologist may request RFTs to check your kidney function. You may also be prescribed medication to reduce your heart rate below 63 bpm, required for clearer imaging. 

A contrast dye is injected to enhance the visibility of your heart’s structure and coronary vessels. After a few minutes, you will lie straight in the scanner while detailed images are captured. 

The procedure takes around 15-20 minutes, after which you’ll be advised to drink plenty of fluids to help flush the dye. Your clinician will review the images and explain the findings, including any recommended next steps.

Types of Cardiac CT Scans

Coronary CT Angiogram

A CT Coronary Angiogram is a non-invasive test that uses advanced X-ray imaging to detect plaque buildup or narrowing of the coronary arteries. An iodine-based dye is injected into your arm while X-rays are released from the CT scanner to collect clear pictures of the heart anatomy and coronary arteries.

CT Cardiac Calcium Score

A CT Calcium Scoring test measures the amount of calcium in your coronary arteries, an important indicator of future heart attack risk. By identifying the calcified plaque within the arteries, your clinicians can get a better understanding of recommending treatment options and preventive measures to support long-term heart health.

Who Needs a Heart CT?

Computed Tomography (CT) of the heart is often recommended when symptoms or a past medical history of a patient indicate a cardiac condition or a structural abnormality. Here are a few common reasons why you should get a 3D heart CT Scan:

Signs of Heart Diseases

A CT of the heart may be advised if you frequently experience chest pain, shortness of breath, palpitations, unexplained fatigue, or dizziness. These symptoms highlight the risk of an underlying coronary or structural heart abnormality.

Family History

Individuals with a family history of heart disease may be advised to undergo a CT cardiac scan for early detection of cardiovascular risks and receive proper treatment.

Coronary Artery Disease

CT Coronary Angiography identifies plaque causing narrowing, or blockages of the coronary arteries, thus minimising the risk of heart disease.

Congenital Heart Diseases

CT imaging of the heart can also reveal congenital heart abnormalities, especially in adults and younger patients. Timely detection can help prevent numerous cardiac problems and future complications.

Detection of Tumours or Lumps

A Cardiac Computed Tomography Scan can detect unusual masses, tumours, or growths around the heart or major vessels, offering detailed insights into further investigation and clinical management.
