Biliary cancer, also known as cholangiocarcinoma, is a primary malignant epithelial neoplasm arising in the bile duct. Cholangiocarcinoma can be classified into intrahepatic, perihilar, and distal cholangiocarcinoma according to anatomic location. Multiphase thin-section computed tomography is the primary imaging modality for diagnosis and treatment planning. MR imaging with magnetic resonance cholangiopancreatography provides additional information for differential diagnosis, complex biliary anatomy, and tumor extent. For preoperative assessment of extrahepatic cholangiocarcinoma, longitudinal tumor extent, vascular involvement, lymph node and distant metastasis, and remnant liver volume are the key features. The adoption of recent advances in imaging techniques enables enhanced image quality and helps to offer optimal treatment options.
胆管癌，又称胆管癌，是一种源于胆管的原发性恶性上皮性肿瘤。根据解剖位置，胆管癌可分为肝内、肝门周围和远端胆管癌。多期薄层 CT 是诊断和治疗计划的主要影像学方法。磁共振成像结合磁共振胰胆管成像（MRCP）可为鉴别诊断、复杂胆道解剖结构和肿瘤范围提供更多信息。对于肝外胆管癌的术前评估，肿瘤的纵向范围、血管侵犯、淋巴结和远处转移以及残余肝体积是关键特征。采用最新的成像技术可提高图像质量，有助于提供最佳治疗方案。
