CT Coronary Angiography

Detailed CT imaging of the coronary arteries to assess plaque and narrowing.

What is a CT coronary angiogram?

A CT coronary angiogram uses a CT scanner, ECG monitoring and intravenous contrast to create detailed images of the coronary arteries. It can help identify coronary plaque and areas of narrowing.

Why it might be requested?

• Chest pain or symptoms suggesting coronary artery disease.
• An inconclusive previous cardiac test.
• Assessment of coronary anatomy.
• Cardiovascular risk assessment in selected patients.

What happens during the scan?

• An initial 12-lead ECG is performed in our clinic with you being briefed by our Cardiologist for safety screening before heading to X-Ray.
• Once you are taken through at X-Ray, ECG electrodes are attached
• Medication may be given to slow the heart rate.
• A cannula is inserted for contrast
• Images are taken while you briefly hold your breath

Preparing for your appointment

• Follow the imaging provider’s fasting instructions
• Avoid caffeine beforehand if instructed
• Bring your medication list
• Tell staff about kidney disease, contrast allergy, pregnancy or possible pregnancy
• Do not stop medicines unless specifically instructed
