A CT scan using electrodes to monitor the heart and an injected contrast dye to produce detailed three-dimensional images of the coronary arteries. It helps assess narrowing or blockages, investigate chest pain and ischaemia, and support treatment planning. Preparation may include avoiding food, drink or caffeine.
