Cardiac CT

A cardiac CT scan is one of the options for routine cardiac examination which is currently increasingly in demand because it can visualize the structure of the heart and its blood vessels clearly in a non-invasive manner. In addition to calculating the calcium score, coronary angiography (imaging of coronary vessels) is also performed, making it also known as “CT Cor”.

Cardiac CT Indications

Usually, your doctor will recommend a cardiac CT in order to:[1,2]

• Assess the presence of risk/suspicion of heart disease (both coronary narrowing and tumor)
• Evaluate your symptoms of chest pain/shortness of breath
• Evaluate anatomical/morphological abnormalities of the heart
• Evaluate heart condition before or after a medical procedure

Calcium Score

A calcium score is an evaluation of calcium deposits in atherosclerotic plaques formed in the coronary arteries. The following is the interpretation of the coronary calcium score.[3]
