Application of three-dimensional magnetic resonance cholangiopancreatography in diagnosis of biliary atresia in children

Objective The aim of this study was to investigate the clinical value of three-dimensional magnetic resonance cholangiopancreatography(3D-MRCP)in the diagnosis of infantile biliary atresia(BA).Methods 24 children with suspected BA were admitted to our hospital between April 2016 and April 2020,and all underwent routine MRI and 3D-MRCP examination.The diagnostic efficacy of MRCP was evaluated by histopathological examination as a gold standard.Results 24 children with suspected BA were successfully completed surgery,andthe pathological examination showed BA in 22(91.7%)children,including BA typeⅠin 2(8.3%),BA typeⅡin2(8.3%)and typeⅢin 18(75.0%),choledochal cyst in 1(4.2%)and normal biliary system in 1(4.2%);the 3D-MRCPdiagnosed BA in 21,choledochal cyst in 1,while misdiagnosed BA as choledochal cyst in 1,and misdiagnosed infantile hepatitis syndrome with normal biliary tract system as BA in 1;the sensitivity of 3D-MRCP in the diagnosis of BA was 95.5%,with the specificity of 50.0%,the accuracy of 95.8%,the positive predictive value of 95.5%,the negative predictive value of 50.0%,and the Kappa value of consistency with pathological diagnosis was 0.455(P<0.05).Conclusion The application of 3D-MRCP has a high diagnostic efficiency for infants with BA,which could guide the clinicians dealing with this entity appropriately early.
