Objectives

Narrative objectives1

Coronary CT angiography is traditionally recommended as a screening test for patients with low-intermediate risk of coronary artery disease. It is renowned for its ability to provide an excellent anatomical assessment of the coronary arteries and its high negative predictive value. While assessing plaque morphology and calcification has been possible for some time, it has only recently become feasible to conduct qualitative evaluations of the coronary arteries and myocardium. This enables the evaluation of inflammation through the pericoronary fat attenuation index (FAI), as well as the assessment of fibrosis and oedema using the extracellular volume fraction (ECV). However, as the relationship between these indicators and patient profiles, echocardiographic findings, coronary catheter findings and prognosis has not yet been fully verified, we will investigate their clinical significance.
