Abstract
The evolution of dual energy computed tomography (DECT) and associated clinical advances continue to permeate the landscape of abdominal imaging. This article reviews general topics and recent contributions pertinent to progressive clinical implementation of this technology. Recent studies underscore the recognition of the dependence of the Hounsfield unit (HU) on keV and the resultant need for the translation of traditional diagnostic criteria. Similarly, critical assessment of virtual unenhanced imaging and its potential to replace true non-contrast imaging has been reflected in a number of studies that explore this critical radiation dose control function. The introduction of novel protocols includes the use of biphasic contrast technique, which, coupled with material discrimination, highlight capabilities unique to the DECT technique.
