Abstract: Objective To demonstrate the imaging characteristics of pancreatic neuroendocrine neoplasm (P-NEN).Methods The CT and MRI findings of 43 cases of P-NEN confirmed by pathology were analyzed,and compared with pathological results.Results Mean size of 43 lesions in 43 P-NEN patients were (25.00± 1.82)mm.Necrosis cystic degeneration were found in 26 lesions.In CT plain scan,15 lesions were isodense,28 lesions were hypodense.All of 43 lesions were hypointensity signal on T1WI;27 lesions were hypointensity signal,16 cases were isointensity signal on T2WI.Twenty-seven lesions showed envelope;30 lesions showed clear outline.In enhancement images,24 lesions were marked enhancement since arterial phase;8 lesions showed delayed enhancement;5 lesions showed centrality enhancement;6 lesions showed wild enhancement.Conclusion P-NEN has some characteristics on CT and MRI scanning,imaging can play an important role in diagnosis for P-NEN.
