The study evaluates four physically motivated constraints in the estimation of the proton density fat fraction (PDFF) based on the physics of magnetic resonance imaging. These were smooth fieldmap, smooth initial phase, nonnegative proton density and moderate $$$R2*$$$ values. Results show that constraints are effective at reducing standard deviation and bias.
