Diagnostic performance of ultrasound-derived fat fraction for MRI-PDFF-defined hepatic steatosis in children: a prospective single-center study
This prospective single-center study of 155 children demonstrates that ultrasound-derived fat fraction (UDFF) is strongly correlated with MRI-PDFF and exhibits high apparent diagnostic accuracy for detecting hepatic steatosis, though the identified cutoff values require external validation before clinical use.
