Figure 2: Axial contrast-enhanced computed tomography images of a 62-year-old male in the pancreatic parenchymal phase showing adenocarcinoma in the head of pancreas (star) and the encasement of superior mesenteric vein (long arrow) and celiac trunk (short arrow) by the lesion. (a) Usual dose with Filtered Back Projection. (b) Reduced dose with Filtered Back Projection. (c) Reduced dose with adaptive iterative dose reduction three dimensional
