Dual energy (DE) CT can add value through: A. Improved visualization of existing image content B. Creation of new image content not otherwise available C. Opportunities to reduce radiation exposure, IV contrast volume, or imaging utilization

1. Physics review of x-ray spectra and tissue absorption at different x-ray energies 2. DE data acquisition and postprocessing including material characterization, 3 material decomposition, virtual monochromatic imaging. 3. Demonstrate potentially game-changing applications (organized per teaching point category letters) via relevant clinical case examples: A: Improved iodine visualization to improve detection and highlight subtle enhancement differences; bone removal in vascular imaging; virtual monochromatic imaging to maximize subtle attenuation differences B: Virtual noncontrast (VNC) and iodine map images for definitive iodine characterization; renal stone characterization; gout identification; bone marrow edema detection; metal artifact suppression C: Avoid further workup by definitive characterization of incidentals; VNC to eliminate noncontrast phases; reduce IV contrast or salvage poorly enhanced scans using low kVp/keV 4. Workflow and post-processing considerations in building a DE program, and needs for successful integration into clinical routine
