摘　　要：目的探讨多层螺旋CT(MSCT)在诊断及鉴别胰腺神经内分泌肿瘤(NETP)中的临床价值。方法选取2017年8月至2019年9月我院收治的NETP患者60例为研究对象,回顾性分析患者一般临床资料,分析患者MSCT影像学检查结果,探讨MSCT在NETP中的诊断价值及对功能性NETP及非功能性NETP的鉴别作用。结果经MSCT检查发现60例患者均为单发情况,即60例患者共60个瘤体,与病理学检查结果一致,包含功能性NETP 34例,非功能性NETP 26例;功能性及非功能性NETP患者瘤体所在处比较无统计学差异(P>0.05);MSCT检查发现,功能性及非功能性NETP患者在边界清晰、囊变、钙化、脾静脉侵犯、淋巴结转移、远处脏器转移的差异无统计学意义(P>0.05),但非功能性NETP患者胰管扩张明显高于功能性NETP患者(P<0.05);功能性NETP患者CT平扫瘤体呈现明显低密度,动脉期、门静脉期、延迟期强化程度高于周围正常组织,非功能性NETP患者CT平扫病灶呈现瘤体呈等密度,动脉期强化程度高于周围正常组织,而延迟期强化程度与胰腺组织相似。结论功能性NETP患者胰管扩张发生情况明显高于及非功能性NETP患者,且功能性与非功能性NETP患者在CT平扫、动脉期、门静脉期、延迟期的病灶均呈现明显差异,可为临床鉴别提供有效依据,值得在临床推广应用。Objective To explore the clinical value of multi-slice spiral CT(MSCT)in the diagnosis and differential diagnosis of neuroendocrine tumors of the pancreas(NETP).Methods Sixty patients with NETP treated in the hospital between August 2017 and September 2019 were selected as the research subjects,and their general clinical data were retrospectively analyzed.The results of MSCT were analyzed to explore the diagnostic value of MSCT in NETP and the role in differential diagnosis of functional NETP and non-functional NETP.Results MSCT examination showed that all the 60 patients had single lesions,that is,there were 60 tumors in the 60 patients,which was consistent with the results of pathological examination,including 34 cases with functional NETP and 26 cases with non-functional NETP.There was no statistical difference in the location of tumors between patients with functional NETP and those with non-functional NETP(P>0.05).MSCT examination found that there was no significant difference in clear boundaries,cystic changes,calcification,splenic vein invasion,lymph node metastasis or distant organ metastases between patients with functional NETP and those with non-functional NETP(P>0.05),but pancreatic duct dilatation was significantly severer in patients with non-functional NETP than those with functional NETP(P<0.05).CT plain scan of functional NETP showed significantly lower density,and enhancement was more intense in the arterial phase,portal venous phase and delayed phase than surrounding normal tissues.CT plain scan of non-functional NETP showed equal density,and the enhancement was more intense in the arterial phase than surrounding normal tissues,while enhancement in the delayed phase was similar to pancreatic tissues.Conclusion The incidence of pancreatic duct dilation is significantly higher in patients with functional NETP than those with non-functional NETP.There are obvious differences in lesions in patients with functional and non-functional NETP in CT plain scan,arterial phase,portal venous phase and delay
