Excerpt
With its high negative predictive value, cardiac computed tomography, CT is optimally suited for the evaluation of patients with a low or intermediate risk of coronary disease, allowing the non-invasive exclusion of coronary disease at relatively low cost and risk [
1‐
35]. Nevertheless, the acceptable radiation dose remains an important issue in cardiac CT. On one hand, using higher radiation exposure levels may put patients at unnecessary risk of radiation damage [
36‐
48]. On the other hand, a too low radiation dose may result in a high level of image noise and therefore in a poor image quality [
49‐
59]. …
