Body Composition of Infants With Biliary Atresia: Anthropometric Measurements and Computed Tomography-based Body Metrics

Study of 80 infants with biliary atresia demonstrates that CT-based body composition metrics (psoas muscle area, skeletal muscle area, fat distribution) provide more accurate assessment of sarcopenia and sarcopenic obesity than traditional mid-upper arm circumference measurements. Findings suggest CT imaging during liver transplant screening can identify at-risk infants requiring targeted nutritional intervention.
