Abstract：
:There is increasing use and popularity of dual-energy computed tomography (DECT) in many subspecialties in radiology. This article reviews the practical workflow implications of routine DECT scanning based on the experience at a single institution where a large percentage of elective neck CTs are acquired in DECT mode. The article reviews factors both on the production (technologist) and on the interpretation (radiologist) side, focusing on challenges posed and potential solutions for seamless workflow implementation.
