CT calcium scoring 

What is CT calcium scoring? 

CT calcium scoring is an imaging diagnostic test that uses Computed Tomography (CT) to measure the amount of calcium present in the coronary arteries and does not require the administration of contrast. This test provides an assessment of the risk of coronary artery disease, even before symptoms appear. 

What is this diagnostic procedure for? 

The main uses of CT calcium scoring are: 

  • Cardiovascular risk assessment: It allows for the assessment of the risk of developing coronary artery disease and cardiac events, such as angina or myocardial infarction. 
  • Early atherosclerosis detection: It helps detect the presence of atherosclerosis (a buildup of plaque in the arteries) at an early stage, even before significant blockages occur. 
  • Guidance for decision-making: It provides useful information for decision-making regarding the treatment and prevention of coronary artery disease, such as the need for lifestyle changes, medications, or additional tests. 

Benefits of advanced technology in CT calcium scoring 

CT calcium scoring offers a number of key benefits thanks to the technology it uses: 

  • Non-invasive: it is a non-invasive test, which means it does not require surgery or incisions. 
  • Quick and simple: It is a quick and simple scan that usually lasts only a few minutes. 
  • Precise quantification: It allows for the precise quantification of the amount of calcium in the coronary arteries, providing an objective measure of cardiovascular risk. 

Early detection: it can help detect coronary artery disease at an early stage, allowing for more timely intervention.

What does the procedure involve?

The CT calcium scoring procedure is relatively simple and is carried out as follows: 

  • Preparation:

    You won’t need to fast or undergo any special preparation before you arrive.
     
  • During the procedure:

    You will lie down on a table that slides into the CT scanner. They will place electrodes on your chest to monitor your heart rate. You will be asked to remain still and hold your breath briefly as the images are taken. You will not be injected with any type of contrast agent. The test lasts approximately 10–20 minutes.
     

    After the procedure: 

    Once the images have been acquired, you can resume your normal activities.

Recommendations for the procedure 

Remember that it is important to adhere to the following recommendations to ensure the quality of the test and your comfort: 

  • Fasting and preparations: No fasting or special preparations are necessary before the procedure. 
  • Medications and allergies: It is important to let us know if you are taking any anticoagulant medication (blood thinners) 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 exposure to radiation. 
  • Aftercare: No special care is required after the procedure. 

Are there any risks? 

In general, CT coronary calcium scoring 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 inserted. It uses a small dose of radiation, which is generally considered low and safe. 

To ensure your procedure runs smoothly, we ask that you arrive before the scheduled time. This will allow us to complete the necessary administrative and clinical preparation. 

Before the procedure, we will give you the Informed Consent form, a document with important information that you must read and sign. 

If your appointment is for an MRI, it is crucial that you inform us about the presence of pacemakers, metallic objects, prostheses (including dental prostheses), tattoos, or drug infusion devices such as insulin pumps.
