Abstract: Disclosed herein are methods, non-transitory computer-readable medium, and systems for determining an estimate of fat within a volume of a subject by determining a parameter ? from the signal intensities of at least three echo signals emitted from a region of the volume of a subject imaged by a magnetic resonance image scanner in response to an applied RF pulse, wherein the three echo signals are taken at a first opposing-phase echo time, a second opposing-phase echo time and an in-phase echo time; and determining a fat volume fraction, f, from the parameter ?.

Abstract: A method for determining an estimate of fat within a volume of a subject comprising the steps of: a) determining a parameter ? from the signal intensities of at least three echo signals emitted from a region of the volume of a subject imaged by a magnetic resonance image scanner in response to an applied RF pulse, wherein the three echo signals are taken at a first opposing-phase echo time, a second opposing-phase echo time and an in-phase echo time; and b) determining a fat volume fraction, f, from the parameter ?.
