Our Approach

A computed tomography (CT) coronary angiogram is an innovative approach to investigating chest pain and your coronary arteries. Instead of immediately performing a conventional invasive angiogram to look for blockages or narrowing, we can create a 3-D image of your arteries using X-rays. If they are clear, you may not need invasive testing.

We use the latest CT scanners when looking for coronary artery disease, offering accurate results and low radiation exposure. If you still need cardiac catheterization after the CT scan, our team offers a range of procedures for diagnosis and treatment.

Risks of Coronary CT Angiograms

While a coronary CT angiogram is a safe procedure, potential risks include:

  • Allergic reaction to the contrast dye, which can range from mild to severe and may include:  
    • Itching
    • Redness
    • Hives
    • Nausea  
    • Difficulty breathing 
    • Kidney failure
    • Very slightly increased chance of cancer, from the radiation exposure, particularly if you have multiple scans over many years
