ultrasound shear wave elastography
DeviceThe investigators have recently published a very small study in neonates/infants with suspected BA showing that US liver shear wave speed (i.e. - liver stiffness) can differentiate BA from other causes of cholestasis, potentially with a very high degree of accuracy. Additional research is needed to confirm these very preliminary results and determine if liver shear wave speed measurements either before or after (including longitudinally) Kasai can predict key outcomes.
