摘　　要：目的探讨肝脏转移性神经内分泌癌的影像学特征,以提高对该病的诊断水平。方法回顾分析肝脏转移性神经内分泌癌的CT及MRI表现,归纳其影像学特点。结果肝脏转移性神经内分泌癌以多发病灶为主,最大直径多在3cm以下,最大直径3cm以上时中心可出现坏死,动态增强扫描病变多表现为边缘强化,门脉期强化明显,部分病变动脉期强化明显。结论肝脏转移性神经内分泌癌的血供特点与原发神经内分泌肿瘤的血供特点有一定的相关性。肝脏转移性神经内分泌癌的影像特征可为临床诊断提供一定的帮助。Objective To investigate the imaging features of hepatic metastases of neuroendocrine carcinomas. Methods Retrospective analysis for imaging features of hepatic metastases of neuroendocrine carcinomas were used on CT and MRI data. Results Hepatic metastases of neuroendocrine carcinomas usually are multiple and the most diameter is less than 3cm. When tumor size is more than 3cm,the necrosis is often observed in the turmors. Most of the hepatic metastases of neuroendocrine carci- nomas has a ring enhancement on dynamic-contrast enhanced CT and MRI. Conclusion The imaging features of blood supply of the hepatic metastases of neuroendocrine carcinomas are correlated with those of the origin tumors. Hepatic metastases of neuroen- docrine carcinomas has some specific imaging characteristics,which may help the differential diagnosis of the tumor.
