DECT enables the synthesis of a wide array of images from a single acquisition because of the availability of CT projection data at more than one polychromatic energy level. Currently, six major approaches are used for DECT.

VMC images-specific to DECT, available with all platforms at multiple keV levels starting from 40 keV. Images at 40–70 keV remain susceptible to pseudo enhancement similar to that on polychromatic single-energy CT images @RadioGraphics @cookyscan1
