This study will evaluate the use of cardiac CT in identifying atherosclerosis plaque in patients who have not been diagnosed with atherosclerosis and who have no symptoms of the disease but who are at risk of developing atherosclerosis based on traditional risk factors such as diabetes or a family history of coronary artery disease.

Condition Intervention Phase
Coronary Artery Disease Procedure: Cardiac CT Early Phase 1

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Prospective Detection of Subclinical Atherosclerosis in Asymptomatic Individuals With High Likelihood of Coronary Artery Disease With a Novel, Low-Radiation Volumetric Computed Tomography Approach
