摘　　要：目的:探析磁共振胰胆管成像联合多层螺旋CT检查在胆道梗阻性疾病诊断中应用价值。方法:选择2022年6月~2023年6月医院137例经内镜逆行胰胆管造影确诊的胆道梗阻性疾病患者作为研究对象,患者均经磁共振胰胆管成像、多层螺旋CT检查,以内镜逆行胰胆管造影为金标准,计算磁共振胰胆管成像、多层螺旋CT检查及两者联合诊断的检出率。结果:磁共振胰胆管成像与胰胆管造影具有理想的一致性(Kappa=0.882),多层螺旋CT与胰胆管造影具有理想的一致性(Kappa=0.763);两者联合与胰胆管造影具有极好的一致性(Kappa=0.967)。以胰胆管造影为“金标准”,磁共振胰胆管成像、多层螺旋CT检查联合诊断胆道梗阻性疾病的灵敏度为97.78%(44/45),准确度为98.54%(135/137),阴性预测值为98.91%(91/92)高于两者单独诊断,差异有统计学意义(P<0.05)。结论:磁共振胰胆管成像联合多层螺旋CT检查在胆道梗阻性疾病诊断中应用价值较高,相较于两者单独诊断能提升诊断效能。Objective:To explore the application value of magnetic resonance pancreatobiliary imaging combined with multilayer spiral CT examination in the diagnosis of biliary obstructive diseases.Methods:137 cases of biliary tract obstructive disease diagnosed by endoscopic retrograde cholangiopancreatography were selected as the study subjects from June 2022 to June 2023 in the hospital,and the patients were examined by magnetic resonance pancreatico-cholangiopancreatic imaging and multislice spiral CT,and the detection rates of magnetic resonance pancreatico-cholangiopancreatic imaging,multislice spiral CT examination and the combination of the two diagnoses were calculated with endoscopic retrograde cholangiopancreatography as the gold standard.Results:Magnetic resonance cholangiopancreatography had ideal agreement with pancreatic cholangiography(Kappa=0.882),and multilayer spiral CT had ideal agreement with pancreatic cholangiography(Kappa=0.763);The combination of both had excellent agreement with pancreatic cholangiography(Kappa=0.967).Using cholangiopancreatography as the“gold standard”,the combined diagnosis of biliary obstructive disease by magnetic resonance cholangiopancreatography and multilayer spiral CT was 97.78%(44/45)in sensitivity,98.54%(135/137)in accuracy,and 98.91%(91/92)in negative predictive value,which was higher than that of both diagnostic tests alone.diagnosis,and the difference was statistically significant(P<0.05).Conclusion:Magnetic resonance cholangiopancreatic imaging combined with multislice spiral CT examination is of high value in the diagnosis of biliary obstructive diseases,and the diagnostic efficacy can be improved compared with the two diagnoses alone.
