Objective To investigate the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) in detecting extrahepatic bile duct stones. Methods A total of 102 suspected extrahepatic bile duct stone patients admitted to our hospital between January 2024 and February 2025 were enrolled. All patients underwent abdominal CT and MRCP scans, with pathological results serving as the gold standard for diagnosis. Results Among the 102 suspected cases, 75 were confirmed positive and 27 negative by pathological examination. Specifically, 58 abdominal CT cases (65 detected) were positive, while 20 (37 detected) were negative. MRCP confirmed 70 positive cases (72 detected) and 25 negative cases (30 detected). MRCP demonstrated diagnostic accuracy of 93.14%, specificity of 92.59%, sensitivity of 93.33%, positive predictive value of 97.22%, and negative predictive value of 83.33%, significantly outperforming abdominal CT (76.47%,74.07%,77.33%,89.23%,54.05%, P<0.05). Conclusion For patients with extrahepatic bile duct stones, MRCP enhances diagnostic efficiency and provides robust evidence for clinical diagnosis and treatment planning, demonstrating significant clinical value.
