Learning objectives

To highlight associations between geometric features of coronary arteries and the extent of atherosclerosis, presenting data from interventional coronary angiography (ICA) and coronary computed tomographic angiography (CCTA) studies.
To define parameters used for the description of coronary artery geometry and show examples of measurements.
To discuss the clinical significance of geometric parameters and implications on imaging technique and reporting.
