Abstract

Purpose: Describe the imaging characteristics of biliary obstruction on 1.5 tesla magnetic resonance. Material and method: Cross-sectional study of 97 patients with biliary obstruction who underwent MRI at Hai Phong International General Hospital. Result: The average age of patients with biliary obstruction was 55.9±16.98, in which biliary obstruction was common in patients > 40 years old, accounting for 77.32%. The male/female ratio was 1.42. The most common location of gallstones on MRI was gallbladder stones, accounting for 64.37%. The location of biliary dilatation on MRI was more common than intrahepatic biliary dilatation, accounting for 62.69%. Common bile duct dilatation accounted for 37.31%. Biliary obstruction in the common bile duct was present in 42 patients (43.31%). Biliary obstruction due to biliary tumors on MRI was mainly biliary tumors, with 8 patients accounting for 57.14%. Biliary stricture images on MRI were present in 4/97 patients, of which non-concentric narrowing, irregular edges, asymmetry, and severe narrowing were the majority. The main cause of biliary obstruction was gallstones, accounting for 89.69%.
