Abstract
Technical advances in CT imaging have improved ability to discriminate different materials, going beyond the attenuation imaging provided by most current systems. Nowadays, dual-energy CT systems allow for material identification and quantification providing qualitative and quantitative information about tissue composition and contrast agent distribution. This chapter explores the general principles of material decomposition analysis, as well as the technical implementations of single- and dual-source CT systems and the clinical advantages and prospects.
