Magnetic resonance cholangiography in the assessment and management of biliary complications after OLT

Figure 10 Sphincter of Oddi dysfunction in a liver-transplanted female patient with cholestasis and abdominal complaint years after orthotopic liver transplantation. Serial 2D cinematic magnetic resonance cholangiography images (A) and (B) acquired after few seconds show redundancy of the reconstructed common bile duct, which appear slightly dilated in the recipient tract, and persistent lack of visualization of the vaterian sphincter complex, with typical “meniscus sign” (arrow) suggesting spasm.
