Abstract:
This article provides an overview of the gamut of biliary imaging techniques currently available to the clinician. It provides a brief history of biliary imaging, particularly intravenous cholangiography, including most commonly used contrast agents. This history is followed by a detailed discussion of modern-day practice modalities, including fluoroscopic and barium cholangiography, CT cholangiography, and magnetic resonance cholangiopancreatography.
