Abstract

Purpose: To assess the value of magnetic resonance imaging (MRI) in the diagnosis of biliary strictures and in differentiation between benign and malignant causes of biliary strictures. Materials and methods: A retrospective and prospective, descriptive study of 75 patients with 76 biliary stricture lesions in Hanoi Medical University Hospital from Jan-2021 to July-2022. Results: Sensitivity, accuracy of MRI for diagnosis of biliary strictures was 97.3% and 94.7% respectively. The κ values calculated for agreement between findings at MRI and those at percutaneous transhepatic cholangiography (PTC) indicated good agreement between the two modalities (0.4 - 0.7). The presence of irregular margin, asymmetry and restricted diffusion of strictured bile duct were significant findings for malignancy (p < 0.001), and accuracy was 85%, 85% and 90% respectively. Conclusion: Magnetic resonance imaging is a valuable modality in the diagnosis of biliary strictures and in differentiation between benign and malignant causes of biliary strictures.
