MRI images illustrates gallstones in the bile duct promoting its dilatation. There is also a small amount of gallbladder sludge.

Case Discussion
MRCP has largely replaced ERCP as the gold standard for diagnosis of choledocholithiasis, able to achieve similar sensitiviy and specificity (approaching 100%) without ionizing radiation, intravenous contrast or complication rate inherent in ERCPs.
Like in this case, filling defects are seen within the biliary tree on thin cross-sectional T2 weighted imaging.
