Synopsis

Biliary MRI has a 95% sensitivity and 97% specificity for the detection of biliary dilatation. The purposes of this presentation are:– to describe imaging features of various obstructive and non-obstructive biliary diseases, providing tips for distinction between dilated bile duct pathologies;– to demonstrate the spectrum of imaging findings of focal or diffuse thickening of gallbladder wall and biliary cystadenoma/carcinoma;– to show other uncommon clinical scenarios where MRI may be useful to demonstrate biliary tree diseases.
