Figure 3a. (a) Sagittal volume-rendered 3D multi-detector row CT scan demonstrates the normal celiac axis (straight arrow) and superior mesenteric artery (SMA) (curved arrow). (b) Coronal volume-rendered 3D multi-detector row CT scan shows the normal branching pattern of the SMA (arrow). (c) Coronal oblique volume-rendered 3D multi-detector row CT scan shows the normal branching pattern of the inferior mesenteric artery (arrows). (d) Coronal volume-rendered 3D multi-detector row CT scan demonstrates the normal mesenteric veins.
