Accurate Point of Care Liver Disease Diagnostics

October 21, 2025 updated by: Claude Sirlin, University of California, San Diego

This research study is being conducted to find out more about techniques to non-invasively evaluate liver disease. The investigators are testing a new technology to evaluate the liver (LiverScope®), and they will compare it to other methods to evaluate the liver, including advanced conventional liver MR and liver FibroScan® ultrasound exams. MR exams and FibroScan® ultrasound exams are common exams used to monitor NAFLD. Conventional MR scanners use magnetic fields and radio waves to make pictures of the liver. LiverScope® is a small, portable MR-based device that uses similar, but simplified technology, and can be used on top of an exam table in an outpatient setting. LiverScope® currently is not approved for clinical use.

In this study the investigators will learn how LiverScope® measurements of the liver compare to MR.

Study participants will be asked to complete a one-time visit which includes:

  • LiverScope exam
  • MR exam
  • FibroScan exam (optional)
  • Blood draw
  • Completion of study questionnaires

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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.

Study Type

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

No

Sampling Method

Non-Probability Sample

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Single arm
This is a single arm study in which all participants undergo the same research procedures.
Diagnostic test: Liverscope® exam
Participants will undergo a LiverScope® examination to measure liver proton density fat fraction (PDFF, primary) and T1 and T2 values (exploratory).
Diagnostic test: MR exam
Participants will undergo an advanced MR examination to measure liver PDFF, T1, T2, and liver stiffness values.
Diagnostic test: FibroScan® exam (optional)
Participants may undergo a FibroScan® exam (optional) to evaluate liver fat and liver stiffness.
Other: Blood draw
Participants will undergo a blood draw (approximately 10 mL) for measurement of CBC, platelets, and complete metabolic panel with transaminases.
Other: Body measurements
Participants will have their height, weight, waist circumference, and hip circumference measured.
Other: Questionnaires
Participants will be asked to fill out questionnaires to collect information about their alcohol consumption, history of cigarette smoking, presence of diabetes, and history of liver disease and medications

What is the study measuring?

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
Repeatability and reproducibility coefficients of LiverScope® PDFF measurements
Time Frame: Up to 3 months
Estimation of repeatability and reproducibility coefficients of liver PDFF values measured by LiverScope®.
Up to 3 months
Agreement of LiverScope® PDFF measurements with MRI PDFF measurements
Time Frame: Up to 3 months
Assessment of the agreement between LiverScope® PDFF measurements and MRI PDFF measurements.
Up to 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Repeatability and reproducibility coefficients of LiverScope® T1 measurements
