It is involved in the production of hormones insulin glucagon and somatostatin and also involved in digestion by its production and secretion of pancreatic juice. Ultrasound evaluation of the normal pancreas cme vital activity provides an overview of normal pancreas anatomy structural and vasculature frames as well as the lab values indicating pancreatic disease.

Ultrasound of the pancreas.
Pancreas anatomy ultrasound. The anterior and posterior superior pancreaticoduodenal veins drain directly into the portal vein. In most cases the transversal and sagittal directions. However the complex anatomy of the organ and surrounding tissues make evaluation a demanding task and the ultrasound echo of even the normal pancreas varies widely from patient to patient.
Use the splenic vein to help identify the pancreas superficial to this. The location of the pancreas in the abdomen makes it well suited for ultrasound examination. The pancreas is a retroperitoneal organ that has both endocrine and exocrine functions.
Tail of pancreas start with the probe transverse then angle the heel of the probe cephalad and left as the tail can be sitting up under the spleen. With the exception of the tail of the pancreas it is a retroperitoneal organ located deep within the upper abdomen in the epigastrium and left hypochodrium regions. The pancreas is an oblong shaped organ positioned at the level of the transpyloric plane.
Thus the spleen can be used as a window and a left intercostal coronal approach can also be utilised. As a general rule each organ and abnormality is imaged in two directions. A longitudinal scan through the upper midabdomen demonstrates the characteristic triad of stomach liver and pancreas.
Pancreatic ultrasound can be used to assess for pancreatic malignancy pancreatitis and its complications as well as for other pancreatic pathology. A common sequence of a full abdominal ultrasound examination is aorta pancreas livergallbladder kidneys bladder region intestines. Preparation fast the patient to reduce interference from overlying bowel gas which may otherw.
The pylorus is characterized by a marked thickening of the muscular coat anterior to the head of the pancreas. 202 pylorus pancreas liver. December 17 2002 by lars thorelius.
The head of the pancreas is drained by the two anterior and posterior inferior pancreaticoduodenal veins which empty into the superior mesenteric vein.
