Milan, Italy ABSTRACT Content In literature there is no clear consensus in acquisition technique in pancreatic endocrine tumors. Objective To assess whether pancreatic phase may replace the arterial one in the evaluation of endocrine pancreatic tumors. Methods Twenty-nine endocrine pancreatic lesions, with definitive morphological and immunohistochemical characterization, after surgical treatment (n=24) or endoscopic-ultrasonography guided fine-needle-aspiration cytology (n=5), were retrospectively evaluated. All lesions were studied with MDCT (16 rows technology) triple-phase technique from December 2004 to August 2006. Images obtained during each phase were separately interpreted by two senior radiologists, experienced in pancreatic pathology, blinded to surgical results. The attenuation of the endocrine tumors and of normal pancreas and the mean absolute tumor-to-gl
