Abstract:
Computed tomographic image slices between 2.5 and 3.0 mm are commonly used for coronary calcium scanning. To evaluate the comparative accuracy of thicker image slices (5 to 6 mm) for predicting coronary events, we acquired both types of scans in 280 research participants and clinically followed them up for 7 years. We found that thick-slice image scanning and image assessment ranked calcium scores similarly and that measurements from both scanning methods predicted coronary heart disease events equally.

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...

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...
