摘　　要：目的:分析256层螺旋CT重组技术与磁共振胰胆管造影(MRCP)在胆管梗阻诊断中的临床应用。方法:选取2015年6月~2023年6月高度怀疑为胆管梗阻患者119例,入院后均接受256层螺旋CT重组技术检查、MRCP诊断。以病理学检查作为金标准,比较诊断结果。结果:256层螺旋CT重组技术检查、MRCP在定位诊断、良恶性定性诊断的准确率中与病理学诊断比较存在明显差异(P<0.05),两者联合诊断的定位准确率、良恶性定性诊断与病理学诊断比较无明显差异(P>0.05)。以胆管梗阻为自变量(非胆管梗阻=0,胆管梗阻=1),以256层螺旋CT重组技术检查、MRCP诊断以及联合诊断为因变量,绘制受试者操作特征曲线,结果显示,联合诊断胆管梗阻的曲线下面积(0.961,95%CI:0.763~0.985)高于单一指标,灵敏度、特异度分别为97.75%、96.67%(P<0.05)。结论:256层螺旋CT重组技术与MRCP均能够实现胆管梗阻的临床诊断,各有优势,两者联合诊断在胆管梗阻的临床诊断中有更高的应用价值。Objective:To analyze the clinical application of 256-slice spiral CT combination and MRCP in the diagnosis of bile duct obstruction.Methods:119 patients were highly suspected of bile duct obstruction in our hospital from June 2015 to June 2023,who underwent 256-slice spiral CT recombinant technology and magnetic resonance cholangiopancreatography(MRCP)after admission.The diagnostic results were compared by using the pathological examination as the gold standard.Results:In the accuracy of localization diagnosis and MRCP and pathological diagnosis(P<0.05),there was no significant difference between the localization accuracy and qualitative diagnosis and pathological diagnosis(P>0.05).Using ROC curve as the independent variable(non-bile duct obstruction=0,bile duct obstruction=1),and 256-slice spiral CT recombinant technique,MRCP diagnosis and combined diagnosis,the ROC curve showed that the combined diagnosis of bile duct obstruction was AUC(0.961,95%CI:0.763-0.985)higher than the single index,and the sensitivity and specificity were 97.75%and 96.67%,respectively(P<0.05).Conclusion:Both 256-slice spiral CT combination and MRCP can realize the clinical diagnosis of bile duct obstruction,each with its own advantages.The combined diagnosis of the two has higher application value in the clinical diagnosis of bile duct obstruction.
