Assessment of the utility of two-dimensional shear wave elastography and superb microvascular imaging in postoperative patients with biliary atresia

Topic overview

Key takeaways

• 2D-SWE liver stiffness values correlate significantly with APRI and FIB-4 indices in postoperative biliary atresia patients
• SMI vascular tree grading is significantly elevated in BA patients compared to choledochal cyst and other hepatobiliary disorders
• 2D-SWE shows promise as a non-invasive tool for monitoring liver fibrosis progression during postoperative BA follow-up
• SMI vascular grading did not correlate with biochemical fibrosis markers, limiting its utility for fibrosis assessment in BA
• SWE values in BA patients were not significantly different from other disease groups, suggesting disease-specific interpretation is needed
