Magnetic Resonance Biomarkers of Fatty Liver Disease
“Technical Validation of MR Biomarkers of Obesity-Associated NAFLD”
The overall goal of this collaborative research program is to develop, validate and translate advanced quantitative magnetic resonance (MR) biomarkers of obesity-associated non-alcoholic fatty liver disease (NAFLD). This protocol represents the research plan for two distinct phases. The first phase is an optimization phase. The second phase is designed to complete a rigorous test of conventional and advanced MRE techniques. Complementary anthropometric, laboratory, and MR measures will also be collected to characterize the cohort and identify factors that affect MRE performance
Magnetic Resonance Elastography (MRE)
The MRE scan will several breath holds and will take approximately 30 minutes to complete.
Diagnostic Test - Liver biopsy
Subjects undergoing WLS will be asked to allow for liver biopsy samples to be collected during their surgical procedure. The collection of these samples will take approximately 5 minutes to complete.
