Objective ToinvestigatethevalueofenhancedCTindifferentiatinggastricneuroendocrinetumors (NET)from gastric neuroendocrinecarcinomas(NEC).Methods 34patientswithpathologicallyprovenneuroendocrineneoplasms (NEN)underwent abdomenenhancedCT.Theage,genderandCTfeaturesofthetumorswereanalyzedretrospectively.TheCTfeaturesincludedtumor location,shape,size,homogeneityofdensity,welldefinedserosalsurface,CTvalueofplainandenhancedCT,enhancementpattern, and metastasesoflymphnode.TheevaluatedparameterswerecomparedbetweengastricNETandgastricNECby t testand Fisher exacttest.Results AsignificantdifferenceingenderwasfoundbetweengastricNETandgastricNEC (P<0.05),however,nosignificant differenceinagewasfound(P>0.05).Thereweresignificantdifferencesintumorsize,shape,welldefinedserosalsurface,enhancement degreeandenhancementpatterninarterialphasebetweengastricNETandgastricNEC(P<0.05),however,nosignificantdifferencesin otherparameterswerefound(P>0.05).Conclusion TheNETofthestomachhascertaincharacteristicsofcontrast-enhancedCT.
