 | | In our series of 79 infants with cholestasis (25 cases of biliary atresia and 54 cases of intrahepatic cholestasis), the accuracy, positive predictive value, and negative predictive value of this TC in the diagnosis of biliary atresia were 94%, 95%, and 93%, respectively. |
 | | As for positive predictive value in the diagnosis of biliary atresia by the ultrasonographic TC coupled with gall bladder shape, it was 100% when positive TC was coupled with an abnormal gall bladder and 88% when positive TC was coupled with a normal gall bladder. |
