Dual-energy computed tomography: concepts, performance, and thoracic applications

J Thorac Imaging. 2012 Jan;27(1):7-22. doi: 10.1097/RTI.0b013e31823fe0e9.


Advances in multidetector technology have made dual-energy computed tomography (CT) imaging possible. Dual-energy CT imaging enables tissue characterization in addition to morphologic evaluation of imaged regions. This article reviews current and potential CT technology, technical and workflow considerations when performing dual-energy CT, and clinical applications in the thorax, with an emphasis on the knowledge gained so far.
