Plaque and Stenosis Imaging
Over the past decade, cardiac Computed Tomography (CT) has developed into a valuable cardiac imaging tool. CT imaging of the coronary arteries allows for non-invasive assessment of coronary atherosclerosis and narrowing of the coronary lumen. Quantitative tools are available to measure lumen dimensions as well as atherosclerotic plaque volumes. Cardiac CT can further be employed to assess coronary bypass grafts and certain types of coronary stents/scaffolds.
Non-coronary Applications and Valve Analysis
Non-coronary applications of cardiac CT include quantification of contractile ventricular function and more recently developed techniques such as myocardial perfusion and late myocardial enhancement imaging. Cardiac CT has excellent three-dimensional spatial resolution and offers unmatched structural assessment of the heart i.e., the left atrium and its appendage and the pulmonary and cardiac veins or valves.
Prior to percutaneous valve interventions, cardiac CT can display the anatomy and dimensions of the left ventricular outflow tract, which is important for procedure preparation and selection of the type and size of devices. In addition, CT can be used to assess peripheral vascular access routes.

CT Syntax Score
The Syntax Score grades the complexity of coronary artery disease from a full coronary tree angiography involving the number of lesions, their functional impact, location, and complexity. The Syntax Score can be used to compare the complexity of coronary artery disease both in individual patients and entire patient cohorts. At the Cardialysis Core Lab, we also apply the newly developed multi slice computed tomography (MSCT)-derived Syntax Score.
Previous and ongoing projects involve quantitative CT angiographic follow-up after percutaneous coronary interventions (PCI), monitoring of bypass graft patency and pre-TAVI evaluations. Our services include study design and CT endpoints, acquisition guidelines, web-based training and certification of CT acquisition sites, CT data handling, independent qualitative and quantitative CT readings.
