1. DECT improves vascular imaging in the abdomen by increasing contrast between vessels and background at low monochromatic energy images and on iodine material density images when compared to conventional CT imaging. 2. Knowledge of the common and variant vascular anatomy of the pancreas and liver are essential for the correct interpretation of DECT images, especially for surgical planning. 3. DECT may facilitate visualization of smaller vessels and therefore improve detection of second order vessels which may improve surgical planning. 4. DECT may facilitate visualization of vascular variants. Better visualization of such variants may improve surgical planning.

1. Brief review of dual energy CT, with description of specific postprocessing techniques to visualize and evaluate hepatobiliary and pancreatic vascular anatomy 2. To review the common and uncommon vascular anatomical variants in the liver and pancreas, including arterial, portal venous and systemic venous anatomy, using multiphasic DECT images  3. To compare various monochromatic energy images (keV) and with iodine-water images 4. To show improved detection of second order vascular supply on DECT 5. To discuss the benefits and pitfalls of the various energies and material specific images in the interpretation of vascular anatomy of the hepatobiliary organs
