Depiction of pancreatic arteries in ND-CM, LD-CM, and VMI+ LD-CM images. ac The posterior pancreaticoduodenal artery arch of one patient who underwent ND-CM (0.8 mL/kg, 400 mgI/mL, and 320 mgI/kg), LD-CM (0.56 mL/kg, 400 mgI/mL, and 224 mgI/kg), and VMI+ LD-CM using the same window level (300 HU) and width (600 HU). The CT value of the aorta was highest on VMI+ LD-CM images (c), lower on ND-CM images (a), and lowest on LD-CM images (b). The posterior pancreaticoduodenal artery arch (white arrow) can be depicted clearly on all images. The anterior inferior pancreaticoduodenal artery (AIPDA) (arrowhead) on LD-CM images (b) cannot be seen clearly, which showed a faint display on VMI+ LD-CM images (c) and can be seen clearly on ND-CM images (a). ND-CM normal-dose contrast medium, LD-CM low-dose contrast medium, VMI+ advanced virtual monoenergetic imaging
