Cardiac CT has become a frequently used diagnostic modality in Denmark, especially for the evaluation of coronary artery disease indicated by angina pectoris/dyspnoea. Indications have recently expanded to include evaluation of valvular heart disease, pre- and post-procedural evaluation related to several invasive procedures as well as some congenital and pediatric cardiac conditions. As described in this review, improved image quality and reduced radiation, owing to technological advances as well as a high number of well-performed scientific studies, have paved the way for this development.
