The radiologic manifestations of cholangiocarcinomas are extremely diverse, since these tumors vary greatly in location, growth pattern, and histologic type. Familiarity with the imaging manifestations of cholangio­carcinomas is important for accurate detection and characterization of these tumors and assessment of resectability. Advances in imaging tech­niques have led to the availability of an array of modalities that, used independently or in combination, can aid in the accurate diagnosis and evaluation of cholangiocarcinomas in preparation for advanced surgical procedures and treatment planning. Response to novel targeted thera­pies can also be assessed with newer imaging tools. Hence, knowledge of current and emerging imaging applications is essential for correct di­agnosis and appropriate management of these tumors.
