B0 field maps can be obtained rapidly using dual echo gradient echo sequences. However in lipid rich tissue this is complicated due to the presence of multiple spectral components, hence requiring many more echoes and thereby increasing scantime. Here we demonstrate that by incorporating the seven most intense lipid resonances in the breast, in-phase echo times can be obtained enabling B0 field mapping with dual echo gradient echo imaging in the human breast at 7T without a bias in lipid tissue.
