Calcium Score

The coronary artery calcium score is a measurement of the amount of calcium in the walls of the arteries that supply your heart muscle, using a special computed tomography (CT) scan of your heart. It shows the amount of hardening of the artery wall (a disease called atherosclerosis) that you have. It tells you about your risk of a heart attack or stroke (brain attack) in the next five to ten years.

CT Coronary Angiogram (CTCA)

CTCA uses a CT scanner to take images of the arteries in the heart allowing for the diagnosis of diseases within the vessels.

Liquid contrast agents are injected into a vein which  increase the density of the blood in the vessels, and allows the inside and outside structure of blood vessels to be clearly visible on the CT Cardiac images.

Medication to reduce blood flow and slow down the heart rate might also be given to make the images even clearer and easier to interpret. This will either be given in tablet form or into a vein through a cannula.

Cardiac Magnetic Resonance Imaging (MRI)


MRI uses a high-strength magnet and radio waves to scan the body and produce images or pictures. MRI does not use ionising radiation, which is required for many other types of imaging, and is not known to have any long-term harmful effects. Cardiac MRI is imaging relating to the heart and how it is working.
