Dual blood supply of the duodenum and pancreas from the celiac trunk and the superior mesenteric artery.

Anterior view of omental bursa, opened to show underlying anatomy. Stomach has been sectioned sagitally; the two parts turned to the left and right.

Anterior view of the omental bursa and its posterior relationships. The greater omentum and gastrosplenic ligament have been cut along the greater curvature of the stomach and the stomach has been reflected superiorly.

Schematic illustration of the duodenum and pancreas in situ with the liver, stomach, colon and small intestines removed. The posterior abdominal area and corresponding "bare areas" are illustrated.

Anterior view of deep anterior surface of gallbladder, vessels in porta hepatis, and fossa of gallbladder. Liver has been reflected superiorly, gallbladder freed from its bed and turned inferiorly and to the right.

Transverse or horizontal (axial) MRI of the abdomen at the level of L1. Image at bottom illustrates level of scan (line C).

Coronal MRI of the abdomen. Image at right shows level of scan (line C).

Anterior view of the duodenum, pancreatic ducts, bile duct, gallbladder and the hepatic duct and its branches. For clarity, the pancreas and liver have been removed. A portion of the gallbladder has been removed to show the inner surface.

Anterior view of the stomach bed. The stomach is excised, the peritoneum of the omental bursa covering the stomach bed is largely removed, as is the peritoneum of the greater sac covering the inferior part of the kidney and pancreas.

Transverse or horizontal (axial) MRI of the abdomen at the level of the lower L2. Image at bottom illustrates level of scan (line E).

Transverse or horizontal (axial) MRI of the abdomen at the level of the lower L3. Image at bottom illustrates level of scan (line F).
