Clinical value of abdominal CT, MR and magnetic resonance pancreaticobiliary duct imaging in the diagnosis of extrahepatic bile duct stones
腹部CT、MR与磁共振胰胆管成像在肝外胆管结石诊断中的临床价值

摘要

目的 探讨腹部CT、MR与磁共振胰胆管成像在肝外胆管结石诊断中的临床价值。方法 本研究共纳入98例高度怀疑为肝外胆管结石患者，纳入时间为2022年3月-2023年3月，先后予以腹部CT和MRCP检查，以消化内镜胰胆管成像检查结果为金标准，统计两种检查方法的诊断准确度、灵敏度及特异度。结果 在本研究纳入的所有研究对象中，有82例消化内镜胰胆管成像检查结果为阳性，其余16例的检查结果显示为阴性；与腹部 CT检查肝外胆管结石的准确度相比，MRCP诊断明显更高（P＜0.05）。结论 在肝外胆管结石诊断中，MRCP检查比腹部CT检查的优势更加显著，体现出更高的准确性，可以为早期疾病诊断带来有效支持，值得推广应用。

Abstract

Objective To investigate the clinical value of abdominal CT, MR and MR imaging in the diagnosis of extrahepatic bile duct stones.
Methods A total of 98 patients with highly suspected extrahepatic biliary stones were included in this study, from March 2022 to March 2023. abdominal CT and MRCP were performed successively, and the results of digestive endoscopic pancreatic biliary imaging were taken as the gold standard, and the diagnostic accuracy, sensitivity and specificity of the two examination methods were counted.
Results Of all the subjects included in this study, 82 digestive endoscopy were positive and the remaining 16 were negative; MRCP diagnosis was significantly higher than the accuracy of abdominal CT (P <0.05).
Conclusion   In the diagnosis of extrahepatic bile duct stones, MRCP examination has more significant advantages than abdominal CT examination, reflecting higher accuracy, and can bring effective support for the diagnosis of early disease, which is worth promotion and application.
