Overview
The study will evaluate the accuracy of hepatic steatosis estimation by thermo-acoustic ultrasound with estimation by MRI-PDFF (Proton Density Fat Fraction) . It will also evaluate the sensitivity of this device in the diagnosis of fatty liver.
Description
Patients with either known or presumed diagnosis of non-alcoholic fatty liver disease who meets eligibility criteria will be included in the study. They will have imaging done to estimate hepatic steatosis by two modalities (MRI - PDFF and thermo-acoustic ultrasound). The estimation obtained by thermo-acoustic ultrasound will be compared with MRI results for accuracy of estimation by the thermo-acoustic ultrasound device. The study will also evaluate the sensitivity of the thermo-acoustic ultrasound device if it can diagnose the presence of hepatic steatosis when hepatic fat content is 15% or less by volume.
Eligibility
Inclusion Criteria:

Exclusion Criteria:
- any metal or electronic implants including but not limited to pacemakers, clips, hips
- known history of pregnancy or becoming pregnant during study period
- unable to understand and sign on written informed consent
