Why the study?

This study aimed to evaluate the diagnostic performance of ultrasound-derived fat fraction for MASLD by comparing it directly with MRI-PDFF and CAP.

Does ultrasound-derived fat fraction (UDFF) accurately diagnose metabolic dysfunction-associated steatotic liver disease (MASLD) compared to MRI-PDFF in adults?

Population

103 individuals, including 53 MASLD patients and 49 healthy controls

Comparison

UDFF vs MRI-PDFF vs CAP

Design

Diagnostic study

Key result

Ultrasound-derived fat fraction demonstrated high diagnostic accuracy for detecting hepatic steatosis with an AUC of 0.981, which was significantly superior to the controlled attenuation parameter.

Structured PICO

Does ultrasound-derived fat fraction (UDFF) accurately diagnose metabolic dysfunction-associated steatotic liver disease (MASLD) compared to MRI-PDFF in adults?

P
Population
103 adults aged 18 to 60 years, comprising 54 patients with metabolic dysfunction-associated steatotic liver disease and 49 healthy controls, evaluated for hepatic steatosis using ultrasound and MRI.
E
Exposure
Ultrasound-derived fat fraction (UDFF) measurement via ultrasound elastography
C
Comparator
Controlled attenuation parameter (CAP) via vibration-controlled transient elastography, and MRI-PDFF (non-invasive gold standard)
O
Outcome
Diagnostic performance (AUC) of UDFF and CAP for predicting MRI-PDFF ≥ 5% (the imaging threshold defining hepatic steatosis in MASLD diagnosis)surrogate

Main Result

Effect estimate: AUC 0.981 (95% CI 0.961-1.000)

Absolute Event Rate: 0.981% vs 0.932%

p-value: p=<0.001

Ultrasound-derived fat fraction (UDFF) provides a highly accurate, non-invasive alternative to MRI-PDFF for diagnosing metabolic dysfunction-associated steatotic liver disease, outperforming the established CAP method.

Limitations

  • Small sample size restricts statistical power for analyzing steatosis severity stratification.
  • Single-center recruitment from a tertiary hospital in China may introduce selection bias.
  • Exclusion of pediatric, geriatric, pregnant, and advanced fibrosis patients.
  • Cross-sectional design precludes evaluation of utility for monitoring progression.
  • MRI-PDFF and UDFF measurements were performed on different days (within 3 days).
  • Proportional bias in Bland-Altman analysis, with UDFF tending to underestimate MRI-PDFF at higher fat content levels

Cite This Study

Jin et al. (2025) conducted a cross-sectional in Metabolic dysfunction-associated steatotic liver disease (MASLD) (n=103). Ultrasound-derived fat fraction (UDFF) vs. Controlled attenuation parameter (CAP) was evaluated on Diagnostic performance (AUC) for predicting MRI-PDFF ≥ 5% (AUC 0.981, 95% CI 0.961-1.000, p=<0.001). Ultrasound-derived fat fraction demonstrated high diagnostic accuracy for detecting hepatic steatosis with an AUC of 0.981, which was significantly superior to the controlled attenuation parameter.
