Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

The calcium-scoring computer tomography or calcium-scoring CT scan detects calcium deposits within the plaque in the coronary arteries.

It detects early coronary calcification and confirms suspected coronary artery disease or CAD, primarily in individuals at intermediate risk, such as those with hypercholesterolemia and hypertension.

During the procedure, position the patient supine on the CT table and attach the ECG electrode to the chest to monitor the heart rate.

Instruct the patient to hold their breath briefly during the scan to ensure clear images. Then, slide the table into the CT scanner, which rotates around the patient's body to take multiple images.

Lastly, results are expressed as a calcium score, quantifying the calcium in the coronary arteries:

A score of 0 signifies no identifiable plaque. Scores 1 to 10 indicate minimal plaque, while 11 to 100 denote mild plaque and low CAD risk.

Scores from 101 to 400 reveal moderate plaque accumulation associated with a moderate CAD risk. A score over 400 indicates extensive plaque, suggesting a high CAD risk.
