Diagnostic and interventional radiology in the management of cholangiocarcinoma
Cholangiocarcinoma is the second most common hepatobiliary malignancy after hepatocellular carcinoma and due to the heterogeneity of the disease with very different diagnostic radiological features, clinical behavior and treatment approaches, imaging studies are essential. Computed tomography (CT) and magnetic resonance (MR) examinations play a dominant role in the detection, characterization, staging and assessment of resectability of cholangiocarcinoma, although ultrasonography (USG) is a common screening examination in indeterminate clinical manifestations Interventional radiology offers a wide range of minimally invasive diagnostic and therapeutic methods, from diagnostic percutaneous biopsies, percutaneous biopsies from tumorous processes growing intraluminally in the bile duct, through therapeutic drainage and stenting in the bile ducts and local ablative therapies. This paper provides an overview of the most advanced imaging techniques for the evaluation of intrahepatic, perihilar, and distal cholangiocarcinoma using classification systems in individual locations. It also highlights the possibilities of using interventional radiology for the diagnosis and treatment of cholangiocarcinoma.
