摘要
目的:评估CT与MRI在肝门部胆管癌的诊断价值。材料与方法:回顾性分析16例经CT与MRI检查且为手术病理证实的肝门部胆管癌的CT与MRI表现,比较两种检查手段对病灶的显示情况及定性诊断的准确率。结果:16例肝门部胆管癌CT与MRI均表现为肝内胆管不同程度的扩张,其中14例肝门部见软组织肿块,2例MRI见胆管壁增厚呈鼠尾状改变,4例门脉受累,6例CT发现淋巴结肿大。CT与MRI定性诊断的准确率及对病灶的显示无明显差异。结论:CT与MRI是检查肝门部胆管癌的有效手段。MRI在显示肝门部肿块的大小、范围及沿胆管壁浸润方面比CT优越,尤其对早期肝门部胆管癌诊断更具价值。
Objective:To evaluate the diagnostic value of CT and MRI in hilar cholangiocarcinoma.Ma terials and Methods:CT and MRI findings of 16cases of hilar cholangiocarcinoma proved surgically and pathologically were reviewed retrospectively.The appearances of the lesion shown and the rate of accurate characteristic diagnosis of lesion by these2modalities were compared.Results:Sixteen cases with hilar cholangiocarcinoma were found to have intrahepatic biliary dila-tion,with soft tissue mass at porta hepatis in14cases,and with portal vein tumor thrombus in4cases.Two of the16cases showed thickening of wall of bile duct only on MRI.Six cases of lymphadenopathy were shown by CT,but only4cases by MRI.There is no significant difference in the rate of accurate characteristic diagnosis and the mode of presentation of lesion between CT and MRI.Conclusion:Both CT and MRI are valid methods in hilar cholangiocarcinoma.MRI is more valuable than CT on presentation of size and range of mass and infiltration of bile duct in porta hepatis,especially in early diagnosis.
