Summary

This study aims to evaluate the diagnostic value of non-invasive diffusion-weighted magnetic resonance imaging (DW-MRI) in detecting neoplastic biliary obstruction.

Detailed description

Both surgeons and endoscopists value accurate approaches for identifying the source of biliary stricture in patients with obstructive jaundice. Cholangiocarcinoma or a benign stricture may cause a biliary stricture. Many imaging methods were used to diagnose the cause of biliary stricture. Diffusion-weighted magnetic resonance imaging (DW-MRI) has emerged as a non-invasive imaging modality that can potentially differentiate between malignant and benign biliary obstructions based on the measurement of water diffusion in tissues. The gold standard of the research is endoscopic retrograde cholangiopancreatography (ERCP) and histology. Patients' diagnoses and follow-up were further verified by ERCP or histopathology.
