摘　　要：目的分析肝内胆管细胞癌超声造影与增强MRI影像学表现特点。方法 8例经手术病理证实的肝内胆管细胞癌,术前行超声造影、增强MRI检查。结果超声造影:动脉期5例周边环状高增强,1例整体均匀高增强,2例整体不均匀高增强;门脉期6例整体为低增强,2例内部呈低增强,周边仍见环状高增强;延迟期均呈低增强。增强MRI:动脉期8例环状高增强;门脉期及延迟期1例环状高增强,7例向心性增强。结论肝内胆管细胞癌超声造影与增强MRI表现不同,可能与疾病的病理特点及两种造影剂在人体内的分布特点有关。Objective To analyse the imaging characteristics of intrahepatic cholangiocarcinoma by contrast-enhanced ultrasound （CEUS） and contrast-enhanced MRI. Methods Eight cases of intrahepatic cholangiocarcinoma were confimed by surgery and pathology, they were examined by CEUS and contrast-enhanced MR[ before operation. Results During arterial phases on CEUS, 5 cases appeared as rim-like hyperenhancement, 1 case appeared as diffuse homogeneous hyperenhancement, 2 cases appeared as diffuse heterogeneous hyperenhancement. During the portal phases, 6 cases appeared as diffuse hypocnhancement, 2 cases appeared as hypoeuhancement intratumour and rim-like hyperenhancement at margin. During lag phases, all cases appeared as hypoenhancement. During arterial phases on contrast enhancement MRI, 8 cases showed tim-like hyperenhanccment. During portal and late phase, 1 case showed rim-like hyperenhancement, 7 cases showed centripetal enhancement. Conclusion Intrahepatic cholagiocarcinoma shows different imaging characteristics on CEUS and contrastenhanced MRI. The pathologic characteristics of the tumor and the distribution characteristics of the two contrast agents in the body may result in the difference.
