Cardiac CT Imaging
Cardiac CT is an imaging test that uses CT technology to visualise the anatomy, coronary circulation and great vessels of the heart.
There are two types of CT scans used in the diagnosis of coronary artery disease (CAD):
- Coronary CT angiography (CTA)
Calcium-scoring is a fast, non-invasive examination used to detect the presence and amount of calcium deposits or plaque accumulation in the coronary arteries. It is considered the most effective way of detecting early coronary artery calcification from atherosclerosis before symptoms develop.
The amount of coronary calcium has been recognised as a powerful independent predictor of future cardiac events and may be used to guide lifestyle modifications and preventative medical therapies to reduce this risk.
A calcium-scoring scan takes only a few minutes to perform and is carried out routinely as part of a coronary CT scan, but may also be requested as a stand-alone examination.
Coronary CT Angiography (CTA)
Coronary CTA has evolved as a fast and effective cardiac diagnostic tool. It produces high-resolution 3-dimensional pictures of the moving heart and great vessels. This allows non-invasive evaluation of the presence and extent of both fatty and calcium deposits or plaque accumulation in the coronary arteries.
