- Establishing the calcification of coronary arteries
CT coronary artery calcification measurement is typically performed together with cardio CT. CT coronary artery calcification measurement can be used to establish calcification of the coronary arteries. They are an expression of coronary artery disease, because healthy coronary arteries do not exhibit any calcium. Using computer-aided analysis, we can use standardized criteria to determine whether and to what extent calcification of the coronary arteries exists.
Using comparable values from a large collection of patients, the risk of the presence of coronary heart disease can be estimated as a function of sex and age. If the exam shows large quantities of coronary artery calcification, then coronary heart disease is more likely. Over the long term, the CT coronary artery calcification measurement can also be used to observe the progression of the disease and the success of corresponding therapeutic measures.
For whom is this exam suitable?
For patients who do not have typical complaints, where there are risk factors such as heart attacks in the family history, diabetes, overweight, or smoking, and where a heart catheter exam is not (yet) indicated. No contrast agent is needed.
Things to know about the CT coronary artery calcification measurement radiation dose
X-rays are used for CT coronary artery calcification measurement. The radiation dosage produced is significantly below 0.5 mSv. This means that the radiation exposure is significantly lower than that which everyone is exposed to from the environment, year after year (approx. 2.5 mSv per year).
The process uses a low dose of X-ray radiation and may be performed only by a radiologist. Please always clarify in advance whether your insurer will cover at least part of the cost of the examination.
