Abstract
The clinical and research applications of dual-energy computed tomography (DECT) are evolving and exponentially growing. In this article, we focus on the different applications of DECT for gastrointestinal (GI) imaging. The basic principles of DECT are important to understand its ability to differentiate tissues via application of two energy spectra. Different DECT techniques and scanners currently used are discussed to highlight their advantages and limitations for generating dual-energy datasets. The advantage of generating virtual non-contrast, virtual monoenergetic, and iodine overlay images will be described for evaluation of bowel pathology, including inflammatory, vascular, and neoplastic conditions, as well as in the setting of acute trauma. This review focuses on the applications of DECT across wide range of GI pathologies throughout the large and small bowel. With continuous research and further development of this technology, the use of DECT in imaging and evaluating the bowel holds a promising future.
