Computed tomography of the coronary arteries with angiography
CT heart coronary angiography is a more advanced X-ray examination than the more common CT heart calcium score. The examination is used to assess the coronary arteries and detect signs of coronary artery disease. It is performed with computed tomography (CT/DT) and combines two diagnostic methods: calcium score and contrast-enhanced coronary angiography.
Calcium score measures the amount of calcification in the coronary arteries and can show early signs of atherosclerosis. A CT angiography is then performed where contrast agents are used to visualize the anatomy of the coronary arteries and any narrowing. The combination makes the examination significantly more comprehensive than calcium score alone and enables a detailed assessment of both plaque formation and the lumen of the blood vessels.
What does the examination show?
CT heart with calcium score and angiography mainly shows two types of information:
- Calcium score the amount of calcified plaque in the coronary arteries.
- CT angiography visualizes the anatomy of the coronary arteries and can detect narrowing or other structural changes.
Calcium score provides a numerical value that reflects the amount of calcification in the coronary arteries. The higher the value, the greater the amount of calcified plaque in the vessels and the higher the long-term risk of cardiovascular disease.
- Score 0 – no detectable calcifications.
- Score 1–99 – small amount of calcification.
- Score 100–399 – moderate amount of calcification.
- Score 400 or higher – pronounced calcification and increased risk of coronary artery disease.
The angiography part of the examination also makes it possible to identify any narrowing in the coronary arteries. During this part of the examination, an intravenous contrast agent is given, which allows the lumen of the coronary arteries to be visualized in detail on a computed tomography scan. This cannot be assessed with the calcium score alone. The method can therefore detect both calcified plaques and so-called soft plaques that have not yet calcified.
After the examination is completed, the images are reviewed by a specialist in radiology and the results are then assessed by a cardiologist. In the report, the findings are weighed against your medical background and any risk factors such as blood lipids, blood pressure, diabetes or heredity.
Can the examination detect coronary artery disease?
Yes. CT coronary angiography is one of the most reliable non-invasive methods for evaluating coronary artery disease. The examination can show both the presence of atherosclerotic plaques and the degree of any narrowing in the coronary arteries.
By combining calcium score and angiography, the examination can:
The examination is often used when coronary artery disease is suspected or when a more detailed assessment of the coronary arteries of the heart is needed.
Free medical advice before the examination
Before the examination, a free medical advice with a specialist in cardiology is always included. During the conversation, the doctor will review your medical background, any symptoms and risk factors for cardiovascular disease.
The purpose is to ensure that CT heart coronary angiography is a medically appropriate examination in your case. If the examination is not deemed medically justified, the order will be cancelled and no examination will be performed.
