Objectives: To investigate the value of coronary calcium scoring (CCS) as a gatekeeper prior to coronary computed tomography angiography (CCTA). Background: CCTA increasingly gains importance for the detection of coronary artery disease (CAD). In general CCS is performed prior to CCTA in order to identify patients with heavily calcified vessels, where CCTA is not expected to provide diagnostic results. However, both CCS and CCTA are associated with radiation exposure for the patients. Methods: Between January 2008 and April 2011, 732 consecutive patients underwent CCTA for suspected or known CAD using 64-slice (…
