Accurate Point of Care Liver Disease Diagnostics
University of California, San Diego
Summary
This research study is being conducted to find out more about techniques to non-invasively evaluate liver disease. This is the second phase of a project in which we are testing a new technology to evaluate the liver (LiverScope®). We will compare LiverScope® to other methods to evaluate the liver, including advanced conventional liver MR exams. MR exams are common exams used to monitor MASLD (also known as 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 second phase of the study, we took what we learned in the first phase to optimize the LiverScope® device and are now testing to see how LiverScope® measurements compare to MR after these optimizations. 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

Interventions
- Diagnostic TestLiverScope® exam
Participants will undergo a LiverScope® examination to measure liver proton density fat fraction (PDFF, primary) and T1 and T2 values (exploratory).
- Diagnostic TestMR exam
Participants will undergo an advanced MR examination to measure liver PDFF, T1, T2, and liver stiffness values.
- Diagnostic TestBlood draw
A blood sample of approximately 10 mL will be collected for routine laboratory tests including complete blood count (CBC) and comprehensive metabolic panel (CMP).
- OtherBody measurements
Height, weight, waist circumference, and hip circumference will be measured.
- OtherQuestionnaire
A questionnaire will be administered to collect demographic information (including age, sex, race, and ethnicity), and medical and social history (including alcohol use, tobacco use, history of diabetes, history of liver disease, and current medications).
