3D model of abdominal aorta, celiac trunc, superior mesenteric artery, renal arteries, proximal iliac arteries and branches in a patient with atherosclerosis. 

Wall thickness of 2mm assigned by postprocessing. Wall thickness was assigned inward toward the vessel lumen. While this resulted in a preserved outer shape of vasculature, it resulted in unreal narrowing of lumen. The inner diameter is sometimes zero in thin vessels.
