Abstract:
:Computed tomography is an established tool in the assessment of cardiac anatomy and function. As demonstrated by single photon emission computed tomography, positron emission tomography, and magnetic resonance, the noninvasive evaluation of coronary hemodynamics is an important step in guiding clinical management. Nevertheless, no single modality has been shown to accurately quantify coronary artery stenosis, evaluate an atherosclerotic plaque's composition for embolic risk stratification, and assess myocardial perfusion. Although not a novel technology, dual-energy computed tomography has undergone significant advancements that have increased interest in this modality's potential clinical cardiac applications. Albeit still in the early stages of development, one can expect additional clinical studies to further develop this important tool for cardiac imaging as more institutions acquire dual-energy compatible scanners.
