摘　　要：目的:探讨肝内周围型胆管细胞癌(IHPCC)的CT及MRI诊断。方法:回顾性分析经手术或活检病理证实的IHPCC 24例,20例行CT平扫和三期增强扫描,5例行MR扫描。结果:CT三期增强扫描强化曲线19例表现为"慢进慢退",1例表现为"快进慢退";MRI T2WI及T1WI上无特异性,3例双回波T1WI同反相位信号未见衰减,DWI上为高信号。结论:IHPCC的CT、MRI有其特征性表现,特别三期增强扫描强化曲线"慢进慢退"表现对于IHPCC诊断尤为重要。MRI同反相位扫描对于IHPCC与含脂质肝脏肿瘤相鉴别可能有帮助。Objective：To explore the CT and MRI value in the diagnosis of intrahepatic peripheral cholangiocarinoma（IHPCC）.Methods：24 patients with pathologically proven IHPCC were enrolled in this retrospectively study.Twenty of them underwent plain and three-phase enhanced CT scan,five received MRI scan.Results：Delayed wash-in and wash-out enhanced curve were revealed in 19 patients and rapid wash-in and delayed wash-out was observed in one in the CT scan group.There was no special imaging findings on MRI routine T2WI and T1WI.However,three patients showed no signal attenuation on the in-phase and out-phase images and hyperintense signal was noted on DWI in the MR group（In-phase and out-phase scanning did not performed in other two patients）.Conclusion：Some characteristic CT and MRI manifestations was found in IHPCC.The delayed wash-in and wash-out enhanced curve of three-phase enhanced CT scan is a important clue in the diagnosis of IHPPC.In-phase and out-phase MRI scanning may be helpful in the differential diagnosis between IHPCC and liver tumors containing lipid.
