CT of coronary artery disease Bastarrika G; Lee YS; Huda W; Ruzsics B; Costello P; Schoepf UJRadiology 2009[Nov]; 253 (2): 317-38Technical innovation is rapidly improving the clinical utility of cardiac computed tomography (CT) and will increasingly address current technical limitations, especially the association of this test with relatively high levels of radiation. Guidelines for appropriate indications are in place and are evolving, with an increasing evidence base to ensure the appropriate use of this modality. New technologies and new applications, such as myocardial perfusion imaging and dual-energy CT, are being explored and are widening the scope of coronary CT angiography from mere coronary artery assessment to the integrative analysis of cardiac morphology, function, perfusion, and viability. The scientific evaluation of coronary CT angiography has left the stage of feasibility testing and increasingly, evidence-based data are accumulating on outcomes, prognosis, and cost-effectiveness. In this review, these developments will be discussed in the context of current pivotal transitions in cardiovascular disease management and their potential influence on the current role and future fate of coronary CT angiography will be examined.|*Coronary Angiography[MESH]|*Tomography, X-Ray Computed[MESH]|Contrast Media[MESH]|Coronary Artery Disease/*diagnostic imaging[MESH]|Electrocardiography[MESH]|Humans[MESH]|Radiation Dosage[MESH] |
