In this work we demonstrate high-resolution bipolar water-fat imaging sequence produces same fat quantification as compared to conventional unipolar water-fat imaging sequence under the same scan time. Images of resolved boundaries in bipolar Proton Density Fat Fraction (PDFF) maps are presented. Fat quantifications of the same regions of interest drawn on bipolar and unipolar PDFF were compared and statistical analysis was performed to evaluate the similarity of the two methods.
