The goal of this study is to use our Thermoacoustic Enhanced Ultrasound device to measure the fat levels in your liver and compare it to the the gold standard MRI PDFF measurements. Participants will have a scan with our device, then they will go have an abdominal MRI completed. The goal is to create a more accessible device to measure liver fat as it is an indicator for overall health and metabolic diseases.
Study participants are 18 or older.
Able to understand, read, and provide written informed consent in English.
Able to tolerate both ultrasound and MRI examinations.
Able to lie flat, or on their side, for 20 minutes and pause breathing for up to 10 seconds.
Metal or electronic implants, including, but not limited to: pacemakers, metal clips, drug delivery pumps, hip implants, and neural stimulation devices, contraindicates for MRI.

Correlation between Thermoacoustic Fat Fraction (TAFF) and the MRI-PDFF
The correlation between TAFF and the MRI-PDFF, will be conducted using the calculation of the cumulative distribution of the correlation coefficient as derived by Guenther
