Quantification of plaque characteristics detected by dual source computed tomography angiography to predict myocardial ischemia as assessed by single photon emission computed tomography myocardial perfusion imaging

Coronary computed tomography angiography (CCTA) is a non-invasive modality that allows the simultaneous visualization of coronary artery disease (CAD) (1). Recent developments in dual-source coronary computed tomography angiography (DSCTA) and post-processing algorithms have made semi-quantitative plaque characterization sufficiently reproducible for clinical purposes (2,3)
