Contribution of acoustic radiation force impulse (ARFI) elastography to the ultrasound diagnosis of biliary atresia

Abstract

The addition of ARFI to a standard abdominal US in the initial workup of the neonate with possible infantile cholestasis can provide reliable information on liver fibrosis and help in the diagnosis of biliary atresia.

Evaluation of Liver, Kidney, and Spleen Elasticity in Healthy Newborns and Infants Using Shear Wave Elastography

“…In children, Noruegas et al reported that the mean SWV value of healthy liver was 1.11 m/s . Hanquinet et al measured the mean SWV value of liver as 1.12 m/s (range: 0.73–1.45 m/s) for children . Matos et al determined the mean SWV value of liver as 1.07 ± 0.10 m/s for a healthy pediatric population, with the possibility of reaching 1.12 m/s in the case of younger children .…”

Current Knowledge in Ultrasound-Based Liver Elastography of Pediatric Patients

“…Close follow up is required post-liver transplantation, for autoimmune liver diseases, alpha-1 antitrypsin deficiency and cystic fibrosis [30,31]. Patients with biliary atresia, which is the most common cause of neonatal obstructive jaundice, would also benefit from non-invasive follow-up assessment after the Kasai portoenterostomy to determine the best timing for liver transplantation [29,32]. Regarding the indications, contraindications and the technique used, we refer to the published literature [33][34][35][36][37][38][39][40][41].…”

Role of Point Shear Wave Elastography in the Determination of the Severity of Fibrosis in Pediatric Liver Diseases With Pathologic Correlations

“…Noninvasive quantitative methods such as point shear wave elastography are used to measure tissue stiffness . An alternative method of biopsy in children is becoming increasingly necessary.…”
