Postoperative biliary adverse events following orthotopic liver transplantation: Assessment with magnetic resonance cholangiography

Figure 4 Anastomotic biliary stricture associated with sphincter of Oddi dysfunction. A: Single-shot thick-slab magnetic resonance cholangiogram shows stricture of both anastomotic site (red arrow) and iuxta-papillary choledocho (white arrow), with dilation of pre- and post-anastomotic biliary tract; B: Maximum intensity projection reconstruction of Gd-EOB-DTPA enhanced T1-weighted LAVA sequence demonstrates regular excretion of contrast-enhanced bile in the extra-hepatic biliary tract at 20 min, while contrast-enhanced bile excretion in the duodenum is not appreciable.
