Heart CT

A cardiac CT (computed tomography) is an imaging procedure that uses X-rays and computer-assisted technology to provide high-resolution images of the heart and surrounding structures. Specifically, coronary CT, also known as coronary CTA, focuses on the visualization of the coronary arteries and is often used to detect calcium deposits and plaques in the vessels, which contributes significantly to the diagnosis, assessment, and risk stratification of coronary artery disease (CAD).

What is a cardiac CT and when is it used?

A cardiac CT is an advanced imaging procedure that uses X-rays to create detailed images of the heart and its structures. It is used to diagnose various heart conditions, including the assessment of abnormalities in the heart structures, aortic diseases, and to detect calcifications in the coronary arteries.

What is a coronary CT and what information does it provide?

Coronary CT is a special form of cardiac CT that focuses on the examination of the coronary arteries. It is primarily used to assess the presence, extent, and severity of calcium deposits and plaques in the coronary arteries, which can be indicators of the risk of coronary artery disease (CAD).

How do I prepare for a cardiac CT or coronary CT?

Before a cardiac CT or coronary CT, it is often recommended to fast for a few hours. It may also be necessary to temporarily adjust or pause certain medications, especially those that could affect the heart rate. Your doctor will give you specific instructions depending on your health condition and the type of examination.

Are there risks with a cardiac CT or coronary CT?

As with any imaging examination that uses X-rays, there is a risk of radiation exposure with a cardiac CT, but this is relatively low compared to other diagnostic procedures. In addition, the iodine-containing contrast agent used in some CT scans can cause allergic reactions or lead to complications in patients with certain pre-existing conditions.

How long does a cardiac CT or coronary CT take and what happens after the examination?

A cardiac CT or coronary CT usually takes only a few minutes, although the entire procedure, including preparation and follow-up, can take about an hour. After the examination, patients can usually resume their normal activities without restrictions in most cases. The results will be analyzed by a radiologist and then discussed with your doctor, who will discuss the results and possible further steps with you.
