Objective:To analyze the application value of abdominal CT and magnetic resonance cholangiopancreatography in the diagnosis of extrahepatic bile duct stones.Methods:70 patients with suspected extrahepatic bile duct stones receiving relevant diagnosis admitted to the hospital from January 2020 to May 2022 were retrospectively analyzed.All patients underwent abdominal CT and magnetic resonance cholangiopancreatography scans for diagnosis.The surgical and pathological results was took as the gold standard,the diagnostic efficacy of the two diagnostic methods was calculated,the detection rate of stones with a diameter of＜8 mm using the two diagnostic methods was calculated,the time spent on the inspection was recorded.Results:Using surgical and pathological results as the gold standard,67 out of 70 suspected patients were positive and 3 were negative,respectively.The coincidence rates between abdominal CT and magnetic resonance cholangiopancreatography were 53(75.71%)and 65(92.86%),respectively.In terms of diagnostic efficacy,the specificity of the two diagnostic methods was compared,with no statistically significant difference(χ2=0,P＞0.05).But the sensitivity and accuracy of magnetic resonance cholangiopancreatography were higher than those of abdominal CT,with statistically significant difference(χ2=8.873,8.776;P＜0.05).Magnetic resonance cholangiopancreatography has a higher detection rate for stones with a diameter of＜8 mm compared to abdominal CT,but the examination time used is slightly longer(χ2=18.746;t=2.613,P＜0.05).Conclusion:When diagnosing patients with extrahepatic bile duct stones in clinical practice,both abdominal CT and magnetic resonance cholangiopancreatography can be used for diagnosis.However,compared to other methods,magnetic resonance cholangiopancreatography has a higher diagnostic accuracy and can provide reliable guidance for clinical treatment.
