Imaging and radiological interventions in extra-hepatic portal vein obstruction

Figure 6 Cholelithiasis and choledocholithiasis. A: MR Axial T2W gradient recalled echo image showing multiple variable sized calculi (arrow) filling the gallbladder; B: Thick-slab two-dimensional MRC image of the same patient depicting additionally choledocholithiasis (arrow). Also note the irregular CBD contour (arrow head) with angulated appearance of suprapancreatic CBD (block arrow) consistent with biliopathy; C: ERC of this patient shows dilated intra and extra-hepatic biliary system (thin arrow) with multiple filling defects (arrow heads) in CBD consistent with calculi; D: Post stone retrieval and biliary stent placement (thin arrow). MRC: Magnetic resonance cholangiography; CBD: Common bile duct; ERC: Endoscopic retrograde cholangiography.
