摘　　要：目的比较MRI延迟期强化扫描与MSCT在诊断肝内胆管细胞癌(ICC)中的应用价值。方法以2015年3月至2021年5月125例疑似ICC患者为研究对象,均给予MRI延迟期强化扫描与MSCT检查,并经术中病理学确诊。比较MRI延迟期强化扫描与MSCT检查结果与病理学检查结果的一致性;以病理学检查结果为标准,比较MRI延迟期强化扫描与MSCT检查对ICC的诊断效能及诊断价值;进一步对ICC的病理类型进行分类,比较MRI延迟期强化扫描与MSCT检查对导管状腺癌的诊断效能及鉴别价值。结果MRI延迟期强化扫描结果与病理学检查结果的一致性(Kappa=0.642)高于MSCT(Kappa=0.464);MRI延迟期强化扫描诊断ICC的灵敏度为91.25%,大于MSCT的80.00%(P<0.05);MRI延迟期强化扫描诊断ICC的AUC为0.812,大于MSCT的0.733(P<0.05);MRI延迟期强化扫描结果与病理学检查结果的一致性(Kappa=0.715)高于MSCT(Kappa=0.399);MRI延迟期强化扫描诊断导管状腺癌的准确度为88.75%,高于MSCT的76.25%(P<0.05);MRI延迟期强化扫描诊断导管状腺癌的AUC为0.890,大于MSCT的0.717(P<0.05)。结论MRI延迟期强化扫描对ICC的诊断价值及诊断灵敏度较高,且对导管状腺癌具有鉴别价值。Objective To compare the application value of MRI delayed enhancement scan and MSCT in the diagnosis of intrahepatic cholangiocarcinoma(ICC).Methods A total of 125 patients with suspected ICC were enrolled as the research objects between March 2015 and May 2021.All underwent MRI delayed enhancement scan and MSCT,and then they were confirmed by intraoperative pathology.The consistency of examination results between MRI delayed enhancement scan,MSCT and pathological diagnosis.Taking pathological examination results as the standard,the diagnostic efficiency and value of MRI delayed enhancement scan and MSCT for ICC were compared.The pathological types of ICC were further classified.The diagnostic efficiency and differential value of MRI delayed enhancement scan and MSCT for ductal adenocarcinoma were compared.Results The consistency of examination results between MRI delayed enhancement scan and pathological diagnosis was higher than that between MSCT and pathological diagnosis(Kappa:0.642 vs 0.464).The sensitivity and AUC of MRI delayed enhancement scan in the diagnosis of ICC were 91.25%and 0.812,higher than those of MSCT(80.00%,0.733)(P<0.05).The consistency of examination results between MRI delayed enhancement scan and pathological diagnosis was higher than that between MSCT and pathological diagnosis(Kappa:0.715 vs 0.399).The accuracy and AUC of MRI delayed enhancement scan in the diagnosis of ductal adenocarcinoma were 88.75%and 0.890,higher than those of MSCT(76.25%,0.717)(P<0.05)(P<0.05).Conclusion The diagnostic value and sensitivity of MRI delayed enhancement scan are high for ICC,which is of differential value in ductal adenocarcinoma.
