CT Calcium Scoring
What is a Calcium Scoring CT?
Calcium scoring CT, also known as “Calcium Score,” is a diagnostic imaging test that uses Computed Tomography (CT) to measure the amount of calcium present in the coronary arteries, and it does not require contrast administration. This test provides an assessment of the risk of coronary artery disease, even before symptoms appear.
What is this diagnostic test for?
The main uses of calcium scoring CT are:
- Cardiovascular risk assessment: Allows for the evaluation of the risk of developing coronary artery disease and cardiac events, such as angina or myocardial infarction.
- Early detection of atherosclerosis: Helps detect the presence of atherosclerosis (plaque buildup in the arteries) at an early stage, even before significant obstructions occur.
- Guidance for decision-making: Provides useful information for making decisions about the treatment and prevention of coronary artery disease, such as the need for lifestyle changes, medications, or additional tests.
Benefits of High Technology in Calcium Scoring CT
Calcium Scoring CT offers a series of key benefits thanks to the technology it uses:
- Non-invasive: It is a non-invasive test, meaning it does not require surgery or incisions.
- Fast and simple: It is a quick and simple test that generally lasts only a few minutes.
- Precise quantification: Allows for precise quantification of the amount of calcium in the coronary arteries, which provides an objective measure of cardiovascular risk.
- Early detection: Helps detect coronary artery disease at an early stage, allowing for more timely intervention.
What does the procedure involve?
The calcium scoring CT procedure is relatively simple and unfolds as follows:
-
Preparation:
You will be asked to come without the need for fasting or special preparation.
-
During the test:
You will lie on a table that slides into the CT scanner. Electrodes will be placed on your chest to monitor your heart rate. You will be asked to remain still and hold your breath briefly during image acquisition. No contrast will be injected. The test lasts approximately 10-20 minutes.
-
After the test:
Once image acquisition is complete, you can resume your usual activities.
Recommendations for the test
Remember that it is important to follow these recommendations to ensure the quality of the study and your comfort:
- Fasting and preparations: No fasting or special preparations are necessary before the procedure.
- Medications and allergies: It is important to notify if you are taking any anticoagulant medication or have any allergies.
- Pregnancy: If you are pregnant or think you might be, it is important to inform your doctor, as the test involves radiation exposure.
- Aftercare: No special care is required after the procedure.
Are there any risks?
In general, calcium scoring CT is a safe and well-tolerated procedure, with no risk of allergic reaction or bleeding since no contrast is administered and no IV line is placed. It uses a small dose of radiation, which is generally considered low and safe.
For your test to go smoothly, we ask that you arrive in advance of your scheduled time. This will allow us to complete the necessary administrative and clinical preparation.
Before the test, we will provide you with the Informed Consent form, a document with important information that you must read and sign.
If your appointment is for a Magnetic Resonance Imaging (MRI), it is crucial that you inform us about the presence of pacemakers, metallic objects, prostheses (including dental ones), tattoos, or medication infusion devices, such as insulin pumps.
