Phase-contrast in areas with a significant fat signal is subject to chemical shift artifacts where the fat signal interferes with the neighboring water signal. The purpose of this work is to present a novel method that combines phase-contrast with T2*-IDEAL water-fat separation to obtain water-fat concentrations and velocity images from a single acquisition. We validate our method using a numerical phantom with different combinations of water-fat concentrations, velocity, and noise, and MRI of a 2D axial section of the neck acquired in volunteers. PDFF comparisons showed a significant agreement between phase-contrast T2*-IDEAL and standard methods.
