This study focused on the
potential of ADC histogram analysis on DW imaging to characterize solid
pancreatic masses. Among the ADC histogram parameters, the entropy of ADC with
every b-value combination showed the highest area under the receiver operating
characteristic curve for distinguishing neuroendocrine tumors from pancreatic
adenocarcinomas and mass-forming autoimmune pancreatitis. The entropy of ADC
might add helpful information in differentiating neuroendocrine tumors from
pancreatic adenocarcinomas and mass-forming autoimmune pancreatitis, especially
in patients with contraindication to contrast agents or with solid pancreatic
masses showing atypical findings at dynamic CT or MRI.
