What Is Cardiac CT (Coronary CT Angiography)?

Cardiac CT, also known as Coronary CT Angiography, is a non-invasive, high-resolution imaging technique used to evaluate the structure and condition of your heart and coronary arteries. It plays a critical role in diagnosing coronary artery disease and other cardiovascular conditions early—before they become life-threatening.

During the scan, a contrast dye is injected into your bloodstream, allowing a CT scanner to capture detailed, 3D images of your heart’s blood vessels.

When Is Coronary CT Angiography Needed?

This test is recommended to detect and monitor various heart diseases, including:

• Coronary artery disease (CAD)
• Pericardial (heart lining) disorders
• Congenital (inherited) heart conditions
• Cardiac masses or tumors
• Heart valve problems and prosthetic valve assessment

It is especially useful for patients experiencing unexplained chest pain, those with abnormal stress tests, or individuals at high risk of cardiovascular disease.

Key Benefits of Coronary CT Angiography

Crystal-Clear Imaging

Capture highly detailed images of the heart and coronary arteries, even in early stages of disease.

Early Detection of Plaques

Visualize both the inside and the walls of blood vessels to detect plaque buildup, which can lead to heart attacks.

Find Hidden Blockages

Even if a stress test is normal, Coronary CT may reveal critical narrowings that would otherwise go undetected.

Personalized Treatment Planning

Helps doctors adjust medications, assess stent patency, and guide decisions for surgical or interventional procedures.

Quick, Painless, and Safe

• Scanning takes just 5–7 minutes
• Total time in the clinic is about 30–40 minutes
• No pain, no sedation, and no downtime
• Well-suited even for patients with claustrophobia

Who Should Avoid This Test?

Although safe for most people, Coronary CT may not be ideal if you:

• Have very small stents (as imaging clarity may be reduced)
• Have recently used erectile dysfunction medications (can cause interactions with contrast medications and lead to low blood pressure)

Your healthcare provider will carefully evaluate your medical history before proceeding.

What to Expect: Step-by-Step Process

???? Before the Scan

• Your doctor will explain the procedure and get your consent.
• Blood tests may be done to check kidney function.
• You'll be asked about any medications you take, especially for blood pressure, heart rhythm, or sexual health.

During the Scan

• A vein is accessed for contrast injection.
• Your heart rate may be controlled with medication for sharper imaging.
• You’ll be guided to hold your breath briefly during the scan to prevent image blurring.
• You may feel a temporary warmth, metallic taste, or urge to urinate—these are normal.

Heart Rate Management

The scan is most accurate when your heart beats around 60 times per minute. Your doctor may help control your heart rate beforehand if needed.

Why Choose Cardiac CT Over Other Tests?

• Reveals anatomical details that stress tests and EKGs may miss
• Monitors post-surgery or stent outcomes effectively
• Offers a detailed look at congenital heart anomalies
• Faster and more comfortable than traditional invasive angiography

Don’t Ignore Your Heart Health

Coronary CT Angiography is a powerful diagnostic tool that helps identify heart disease early—when it’s most treatable. If you're experiencing symptoms like chest pain, shortness of breath, or if your doctor recommends the test, don’t delay.
