Pancre as Loc atio - The pancreas n traverses the body, extending from the duodenum to the hilum of the spleen. - Pancreatic head and uncinate process are anterior to the IVC. - The uncinate is posterior to the superior mesenteric vein(SMV). - The pancreatic neck is anterior to the superior mesenteric vein.  -The pancreatic body is posterior to the stomach. - The pancreatic body is anterior to the splenic vein , superior to mesenteric artery(SMA), left renal vein and aorta. - The pancreatic body and tail are inferior to the splenic artery. - The pancreatic tail is anterior to the splenic vein and left kidney. Anamedial curve of tom the duodenum and y immediatel y anterior to the IVC. - The anterior to posterior dimensions of the head range  neck , immediately anterior to the splenic vein , and extends left lateral toward the pancreatic tail. - The anterior to posterior dimensions of the body range from 1 to 2 cm.

The contour of the normal pancreas should always be smooth. Wirsung’s duct (Main) and Santorini’s duct (Accessory) are anechoic tubular structures with echogenic walls.  (6) Nor - mal Size.
