Synopsis

Keywords: High-Field MRI, High-Field MRI, Fat & Fat/Water Separation

Motivation: Nonalcoholic fatty liver disease (NAFLD) is an escalating health issue, necessitating precise noninvasive measurement of hepatic steatosis.

Goal(s): To evaluate the feasibility and accuracy of 5T magnetic resonance spectroscopy (MRS) for in vivo liver fat quantification.

Approach: The study utilized phantoms with controlled fat content and 20 volunteers, comparing proton density fat fraction (PDFF) values measured by 5T MRS against those from 1.5T MRS.

Results: The 5T MRS demonstrated strong consistency with 1.5T measurements, validating its potential in clinical diagnostics despite technical challenges associated with ultra-high-field MRI applications.

Impact: The study's validation of 5T MRS for liver fat quantification could enhance diagnostic precision for liver conditions, influencing clinical practices and guiding future technological advancements in MRI diagnostics.
