Title: Diagnosis of DCE MRI for nonfunctioning pancreatic endocrine tumors
Abstract: Objective: To investigate the appearances and diagnostic value of dynamic contrast enhanced(DCE) MR for nonfunctioning pancreatic endocrine tumors.Methods: DCE MR in 13 cases and clinical data which were proved to be nonfunctioning pancreatic endocrine tumor by pathology were analyzed retrospectively.Results: There were 7 solid tumors and 6 solid-cystic tumors,the maximum diameter was 28~122 mm,the average diameter was 74 mm.All tumors MR T1WI showed equal or low signal and T2WI showed high signal on non-contrast scan.On dynamic contrast enhanced scan,most tumors showed obvious continued enhancement,the cystic area without enhancement.Envelope can be seen in the edge of 12 cases,showed low signal on non-contrast scan and obvious delayed enhancement on dynamic contrast enhanced scan.Conclusions: Central tumors always showed single large mass and with clear boundary,DCE MR is useful for the diagnosis.
