The objective of this study is to compare a standard coronary CT angiography scan protocol
with conventional image reconstruction with a scan protocol using reduced tube current and a
new image reconstruction algorithm. The investigators hypothesize that the image quality of
the new scan protocol is not inferior, while radiation dose estimates are reduced by around
Secondary endpoints of the study include quantitative image quality parameters, prevalence of
non-diagnostic studies, prevalence of coronary artery plaques and plaque characteristics
(calcified, non-calcified, mixed) and prevalence of follow-up examinations.
