Thermoacoustic Method for Estimating Liver Fat Fraction

January 5, 2026 updated by: Endra Lifesciences

Thermoacoustic Method for Estimating Liver Fat Fraction - Pilot Study I

The goal of this study is to use our Thermoacoustic Enhanced Ultrasound device to measure the fat levels in your liver and compare it to the the gold standard MRI PDFF measurements. Participants will have a scan with our device, then they will go have an abdominal MRI completed. The goal is to create a more accessible device to measure liver fat as it is an indicator for overall health and metabolic diseases.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will perform thermoacoustic fat measurements for up to 80 participants, over the span of the study. MRI-PDFF sequences will be acquired for participants in the study to establish a true measure of liver fat content, per the MRI gold standard. Determine the correlation between FLIP CID system Fat fraction results and the MRI-PDFF. Determine the accuracy between the fat measures obtained by the FLIP CID system participants who received a quantitative MRI. The following additional parameters will be evaluated endpoints: Sensitivity, Specificity ,Positive and negative predictive value (PPV, NPV) and The area under the ROC curve for the detection of liver fat abnormalities

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Study Participants will be from the local general population with focus on potential study participants with known, or clinically suspected, elevated fatty liver

  • Able to understand, read, and provide written informed consent in English.
  • Able to tolerate both ultrasound and MRI examinations.
  • Able to lie flat, or on their side, for 20 minutes and pause breathing for up to 10 seconds.

Exclusion Criteria:

  • Metal or electronic implants, including, but not limited to: pacemakers, metal clips, drug delivery pumps, hip implants, and neural stimulation devices, contraindicates for MRI.

  • Liver diseases other than MASLD/MASH/fibrosis including, but not limited to:
  • Cirrhosis
  • Hepatocellular carcinoma
  • Ascites
  • Patients with broken, or injured skin, in the right upper abdominal quadrant.
  • Body habitus, or anatomical variation, where the liver capsule is not accessible with ultrasound through the patient's right intercostal imaging window used in conventional ultrasound liver imaging.
  • BMI greater than 50 kg/m2
  • Patients with subcutaneous fat at measurement location less than or equal to 6mm.
  • Patients with a missing liver lobe.
  • Patients with peri-hepatic fat in the measurement location.
  • Patients with focal liver lesions or anatomical structures in the measurement location, as detected by ultrasound.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Correlation between Thermoacoustic Fat Fraction (TAFF) and the MRI-PDFF
Time Frame: From enrollment until the statistical analysis is reviewed, typically 2 weeks after last MRI data is received.
The correlation between TAFF and the MRI-PDFF, will be conducted using the calculation of the cumulative distribution of the correlation coefficient as derived by Guenther
From enrollment until the statistical analysis is reviewed, typically 2 weeks after last MRI data is received.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 15, 2025

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
