Coronal T2 weighted images shows well defined hypointense areas of various sizes in the dependent portion of the body of gallbladder. There is obstruction at the distal CBD with dilatation of the proximal CBD and intrahepatic biliary system. The hyperintense bile produces a "convex margin" at the site of obstruction which is fairly specific for "meniscus sign of choledocholithiasis".
Axial T2 weighted images shows “target sign” in the distal CBD, representing a central hypointense filling defect surrounded by hyperintense bile.
