The diagnostic quality and availability improved, while data on the actual use of CCTA is sparse.

The most common primary diagnoses of the in-hospital CCTA scans were aortic valve diseases (28.7%), atrial fibrillation and flutter (19.5%), and CAD (16.4%). The majority of CCTA scans was performed in urban hospitals (59.3%). Over time, the number of CCTA substantially increased (factor 11). Among all cases with the primary diagnosis CAD (n\u2009=\u200912,153,473), a minority of 78,199 (0.6%) underwent CCTA scans. Among CAD, younger patients and more females received a CCTA scan and in these cases less invasive coronary angiographies and interventions were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>CCTA is increasingly used in cardiovascular care.
