Paper Abstract

Using ultrafast computed tomography (CT) for calcium quantification offers a potentially non- invasive way to evaluate the presence and severity of coronary artery disease. The currently applied index of ultrafast CT coronary calcium amount is the coronary calcium score of Agatston et al., but this score has not been thoroughly evaluated as to its accuracy and stability. In the present research we estimate the grey scale non-uniformity within the vascular blood pools in the anterior-posterior axis, and in the cephalad-caudad axis. We then estimate the effects of these non-uniformities on coronary calcium scores.
