Abstract: Methods for measuring liver fat mass are provided. One method includes acquiring dual-energy two-dimensional (2D) scan information from a dual-energy X-ray scan of a body and generating a dual-energy X-ray image of the body using the 2D scan information. The method further includes identifying a region of interest using the dual-energy X-ray image and determining a subcutaneous fat mass for each of a plurality of sections of the region of interest. The method also includes determining a liver fat mass for the region of interest based on the determined subcutaneous fat mass for each of the plurality of sections.
