Summary

This study aims to create a 3D model of the bile ducts using MRI and CT scans, along with an AI tool to help doctors guide a camera during a procedure called ERCP. The goal is to improve safety and accuracy. The study will use existing medical images from 100 adult patients who have already had ERCP for bile duct narrowing.
