This study aims to evaluate the diagnostic value of non-invasive diffusion-weighted magnetic resonance imaging (DW-MRI) in detecting neoplastic biliary obstruction.
Adult patients (≥18 years) with clinically suspected biliary obstruction (e.g., jaundice, elevated liver enzymes, cholestasis).
Patients who are scheduled for magnetic resonance cholangiopancreatography (MRCP) and have undergone conventional imaging [ultrasound or computed tomography (CT)].
Patients who will undergo further invasive procedures, e.g., endoscopic retrograde cholangiopancreatography (ERCP), biopsy.
Patients with contraindications to magnetic resonance imaging (MRI) (e.g., pacemakers, metal implants).
Patients who have previously undergone major biliary surgery or stent placement.
Pregnant or lactating women.
This is a prospective, observational, diagnostic accuracy study. The study will include patients with suspected biliary obstruction, referred to our hospital for diagnostic imaging.
