A
  1. Superior mesenteric vein

2. Splenic confluence

26
Q

How does the SMV help up locate the neck and uncinate process?

A

27
Q

How does the splenic confluence help us locate the neck and uncinate process?

A

It is posterior to it

28
Q

What are the landmarks for the body of the pancreas? (3)

A
  1. Superior mesenteric artery
  2. Portosplenic vein
  3. Superior mesenteric vein
29
Q

What is the easiest landmark for the body?

A

A

It is medial anterior to it

31
Q

What landmark helps us locate the tail of the pancreas?

A

The splenic vein
