Dual-Energy CT for analyzing extracellular volume fraction: A promising novel technique in myocardial fibrosis diagnostics?

Dual-Energy computed tomography (DECT) of the heart has become a widely used imaging technique following CT hardware and software advancements, particularly using scanners with greater detector and faster gantry rotation times.1 Each of the major vendors currently provide the ability for acquiring DECT data (also termed spectral or multi-energy CT). In general, DECT uses dual image acquisition at different kilovoltage levels of the same scan volume to facilitate material separation. Based on that principle, DECT provides additional image reconstructions that potentially allow for more comprehensive, accurate and robust CT analysis.
