Transient elastography and sonography for prediction of liver fibrosis in infants with biliary atresia

2014 Journal of ultrasound in medicine 33;5 (853-864)

OBJECTIVES: The purpose of this study was to assess the diagnostic performance of transient elastography and sonography for noninvasive evaluation of liver fibrosis in infants with biliary atresia. METHODS: Forty-seven infants with biliary atresia who underwent both transient elastography and sonography before surgery were included in this study. Two types of transient elastographic probes were used: an M probe, which is used for the general adult population; and an S probe, which is specific to children. Transient elastographic measurements and sonographic findings such as triangular cord thickness and hepatic artery and portal vein diameters were compared with the METAVIR histopathologic fibrosis scoring system. RESULTS: Only transient elastography (rho = 0.63; P
