摘要：

Dual-energy CT uses Lvvo different X-ray spectra enabling material differentiation by analyzing the material-dependent photo-electric and Compton effects. By doing so, dual-energy data provides information beyond the morphological information that is normally provided by single-energy CT. This article reviews principles and discusses clinical and potential forensic applications of dual-energy CT. (C) 2013 Elsevier Ltd. All rights reserved.
