Dual-energy and spectral energy computed tomography: Oncological body applications in clinical use

Dual-energy computed tomography (DECT) is an innovative, evolving technology that allows improved differentiation and quantification of materials, placing CT more on par with magnetic resonance (MR) imaging than ever before. The post-processed DECT series is analogous to the multitude of MR sequences in that it increases the confidence and accuracy of the radiologist and allows specific conclusions to be drawn that can be more valuable to the clinical service. With faster processors and enhanced post-processing techniques, DECT examinations can now be produced and interpreted in a timely manner, which makes this emerging technology clinically relevant. DECT is useful in numerous current body applications, including improved characterization of lesions and improved initial staging and post-therapy evaluation of neoplasms.
