CT Coronary Angiogram (CTCA)

 
 
 
 
 
 
A computerised tomography (CT) coronary angiogram is a non-invasive imaging technique that uses a powerful x-ray machine to produce images of the arteries that supply blood to your heart. It might be used to diagnose the cause of your chest pains or other symptoms, by checking for blocked or narrowing arteries (coronary artery disease).
