Digital subtraction angiography and computed tomography angiography of predominant artery feeding pancreatic body and tail.

Background: Recently a considerable number of promising clinical trials have been designed to perform infusion of stem cells by pancreatic arterial intervention to improve the endocrine function of the pancreas for better diabetes control. It is necessary to investigate the pancreatic body and tail (PBT) arterial system for human islets located mostly in the PBT and identify the predominant artery or arteries. However, the arterial system in the PBT is complicated and variable.
