Study summary

This study aims to evaluate the diagnostic utility of ultrasound-derived fat fraction (UDFF) in assessing hepatic steatosis in patients with suspected metabolic dysfunction-associated steatotic liver disease (MASLD). Using a prospective, cross-sectional design, the study will compare UDFF results with established diagnostic methods, including liver biopsy, MRI proton density fat fraction (PDFF), and controlled attenuation parameters (CAP) measurements. The ultimate goal is to determine if UDFF can serve as a non-invasive alternative to liver biopsy for diagnosing and staging hepatic steatosis, potentially reducing the need for invasive procedures in MASLD management.

Read the detailed description

This prospective observational study, conducted at a single tertiary institution, will investigate the efficacy of ultrasound-derived fat fraction (UDFF) and point shear wave elastography (p-SWE) as non-invasive methods for quantifying liver fat content and fibrosis in patients scheduled for liver biopsy or surgery. The study will enroll 150 participants, suspected of MASLD and who are candidates for liver biopsy or resection.

The study will utilize Siemens ultrasound equipment to measure the UDFF using attenuation coefficient (AC) and backscatter coefficient (BSC) values for liver fat quantification. Additionally, TE parameters, such as controlled attenuation parameter (CAP) and liver stiffness measurement (LSM), will be recorded for comparison. The primary outcomes will assess UDFF's diagnostic accuracy against liver biopsy and MRI-PDFF. Secondary outcomes will include assessment of intra- and inter-observer variability, and correlations with patients' clinical data, such as BMI, liver fibrosis stages and liver function tests.

Expected benefits include validating UDFF as a reliable, non-invasive alternative for liver fat assessment, potentially reducing the need for invasive biopsies in managing liver disease.

Interventions

  • Diagnostic testUDFF

    Ultrasound-Derived Fat Fraction (UDFF) is a quantitative ultrasound technique used to assess hepatic steatosis by measuring the amount of fat in the liver tissue. UDFF estimates fat content using specific ultrasound parameters, namely the attenuation coefficient (AC) and backscatter coefficient (BSC). The AC measures the rate at which ultrasound waves weaken as they pass through the liver, which correlates with fat content, while the BSC quantifies the amount of reflected ultrasound signal, providing additional insights into liver tissue characteristics.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2024 (actual). Primary completion is estimated for Jun 2025, 12 months after the start.

Of 142 non-industry observational studies under Fatty Liver, half reached primary completion within 45 months of starting (the median), counting those still running; a quarter within 20 and three quarters within 122. This study's planned 12 months is below that.

Counting every sponsor, half of 152 studies reached it within 39 months; a quarter within 20 and three quarters within 120.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
