The effect of heart rate, vessel angulation and acquisition protocol on the estimation accuracy of calcified artery stenosis in dual energy cardiac CT: A phantom study

Coronary Computed Tomography Angiography (CCTA) has been a well established non-invasive technique for the assessment of coronary artery disease (CAD). Despite the advances in CT technology, the artifacts caused by cardiac motion at high heart rates still remain a major issue in the interpretation of cardiac CT images since they affect delineation of coronary anatomy and reduce the ability of physicians to accurately assess stenotic coronary lesions [1,2]. Another deficiency of CCTA is the difficulty in evaluating vessel segments with extensive calcified plaque.
