The main limitation of our study is that we didn't have any neuroendocrine tumors. And it can be challenging to differentiate high grade neuroendocrine tumor from adenocarcinoma. Also we didn't symptoms like lesion configuration, main pancreatic duct dilation and others in differential diagnosis. Sure their usage can dramatically improve diagnostic efficiency of the method.

Perfusion CT is a usefull method that allows to visualize and differentiate the nature of pancreatic lesions. Pancreatic adenocarcinomas can be differentiated from benign lesions on the basis of their perfusion characteristics. The most efficient perfusion map is mean transit time.
