The purpose of this exhibit is: 1) To introduce Dual Energy/Spectral CT, and discuss it’s benefits over single source CT. 2) To discuss the applications of DECT in emergency abdominal imaging. 3) To introduce future uses for DECT.

-What is Dual Energy /Spectral CT? How it works the physics behind it. Differences between Dual Energy and Spectral CT -Benefits vs Single Source CT Color Iodine overlay maps, quantification of iodine Characterization and composition of tissue Bone Iodine substraction for vascular analysis Virtual Non-Contrast imaging, and how it works Monoenergetic imaging -Applications of DECT in emergency abdominal imaging (images and examples for each) Bone Iodine subtraction for vascular analysis ie Aneurysms Contrast extravasation for non contained vascular injuries Characterization of renal calculi: Uric acid versus calcium Oxalate stones Bowel Ischemia Trauma: Pancreatic Injuries Calculation of VNC for reduction of dose and clinical applications in vascular, renal , pancreatic , liver and bowel analysis. -Future applications of DECT/Spectral
