Assessment of coronary artery remodelling by dual-source CT: a head-to-head comparison with intravascular ultrasound

Abstract

Coronary CT angiography allows analysis of coronary artery remodelling. The degree of positive remodelling is typically overestimated by CT. A threshold of 1.1 for the RI may be optimal to classify plaques as 'positively remodelled' in coronary CT angiography.
