Abstract:
Awareness of coronary artery calcium scanning by computed tomography as a reproducible, low-radiation dose means to estimate plaque burden in patients necessitates clinical recommendations for interpretation. Coronary artery calcium scanning is best applied in the intermediate risk, asymptomatic adult population. Calcium scores >100 or >75th percentile transform the intermediate risk patient to high risk with recommendations for more aggressive therapy. Scores exceeding the 90th percentile or >400 define the group at the highest risk of a cardiovascular event and may suggest further cardiac testing. Scores from 11 to 100 and <75th percentile confirm intermediate risk status, and scores from 0 to 10 and <75th percentile convert the patient to low or very low risk.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
