CT coronary angiogram and calcium score
A detailed CT scan of the coronary arteries.
What it is
A CT scanner takes very fast pictures of the heart after an injection of contrast through a vein in the arm. It shows plaque and narrowing in the arteries. A calcium score uses a shorter scan without contrast to measure calcified plaque.
Why it may be recommended
- Chest pain where coronary disease needs to be ruled in or out
- Refining heart risk with a calcium score
Before the test
- Avoid caffeine on the day
- A tablet to slow the heart rate may be prescribed for the night before and the morning of the scan
Afterwards
- Drink plenty of water afterwards
Risks
A small radiation dose, and rarely a reaction to the contrast.
