Interventional radiologists play a key role in the diagnosis and management of patients with benign and malignant biliary disease. Sophisticated noninvasive tools such as magnetic resonance cholangiopancreatography (MRCP) and computed tomographic cholangiography (CT cholangiography) can be used to identify biliary pathology. More invasive techniques such as percutaneous transhepatic cholangiography (PTC) and transhepatic image-guided biopsy can be used to clarify the extent of disease and secure a diagnosis. Once a diagnosis has been determined, patients with biliary obstruction or leak may benefit from percutaneous drainage as a prelude to definitive surgical intervention or as a palliative treatment for patients with malignant obstruction.
