简要总结
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
