Artifacts of the common bile duct caused by duodenal metallic hemoclip on magnetic resonance cholangiopancreatography.

Magnetic resonance cholangiography (MRCP) is a non-invasive and highly sensitive diagnostic modality for pancreatobiliay lesions, which can replace the role of Endoscopic Retrograde Cholangiopancreatography (ERCP). However metallic components can lead to misinterpretation of the images of MRCP. Here we present a case of a duodenal metal hemoclip, producing a susceptibility artifact of pathologic lesion in the common bile duct on MRCP.
