Computed Tomography Advances in Oncoimaging.

By illuminating materials with two distinct energy spectra, dual-energy CT (DECT) can provide qualitative and quantitative information regarding tissue composition. Over the last decade, tremendous advances in x-ray tube engineering and software development have spurred the resurrection of DECT. This phenomenon has been paralleled by an ever-growing body of research and incremental clinical utilization, especially in the area of body imaging.This review article discusses fundamental DECT principles, imaging reconstruction, and workflow essentials, as well as aims to provide the reader with an overview of most relevant abdominopelvic applications.
