Abstract

Techniques, apparatus and systems are described for using parameters including chain length, number of double bonds and number of double-double bonds of a complex, magnetic resonance imaging (MRI)-generated fat spectrum to determine the composition and properties of fat and to perform various diagnostic functions. In one aspect, a method using MRI to characterize fat includes acquiring a magnetic resonance (MR) image that includes MR data from a target, determining fat characterization parameters based on the acquired MR data, and using the determined fat characterization parameters to produce a relationship between regions of fat and/or water in the MR image.
