This document provides an anatomy tutorial on abdominal CT scans. It identifies and labels key abdominal structures visible on CT images, including the stomach, pancreas, inferior vena cava, celiac artery and its branches, superior mesenteric vein, abdominal aorta, ovaries, and rectum. The tutorial also notes the normal appearance and location of these structures to aid in anatomical identification on abdominal CT scans.

3. Identify the following structures in the body CT to the right. To view the location of the structure in the image click on
the label at the left and the structure will be indicated in the image. Abdominal CT scans typically begin just above
the diaphragm, so the first slice you see is of the lower chest.

34. CELIAC
• Branching from the aorta 'anterior to the
T12‘ one of three anterior/ midline branches of the
abdominal aorta (the others are the superior and inferior
mesenteric arteries).

35. CELIAC ARTERY BRANCHES
• Left gastric artery
• Common hepatic artery
• Splenic artery

46. SUPERIOR MESENTERIC VEIN
• In anatomy, the superior mesenteric vein (SMV) is a blood vessel
that drains blood from the small intestine (jejunum and ileum).
• At its termination behind the neck of the pancreas,
• the SMV combines with the splenic vein to form the hepatic portal vein.
• The SMV lies to the right of the similarly named artery, the superior
mesenteric artery, which originates from the abdominal aorta.

origin: Continuation of descending thoracic aorta at T12
• course: descends anterior and slightly to the left of the lumbar vertebral
bodies.
•Bifurcation of aorta:L4
• Note that the bifurcation (union) of the inferior vena cava is at L5and
therefore below that of the bifurcation of the aorta)
