Morpho-functional imaging of coronary anatomy and left ventricular perfusion obtained by cardiac CT

Cardiac CT is used in clinical practice mainly to study coronary anatomy, however it allows the examination of the entire heart volume with high spatial and density resolution. Thus, additional pieces of information are potentially available which can be exploited together with coronary morphology. In particular, the simultaneous evaluation of coronary anatomy and myocardial perfusion is crucial for an accurate evaluation of obstructive atherosclerotic coronary plaques. In this study we aimed at building 3D integrated representations of coronary vessels and myocardial perfusion from cardiac CT angiography scans. Qualitative evaluation of CT myocardial perfusion imaging was carried out in comparison with PET blood flow imaging.
