Fat-suppressed 3D fast gradient echo imaging with contrast agent injection is presently in widespread clinical use. The existing approaches of fat suppression (FS), however, are sensitive to field inhomogeneity and suffer from partial application of FS pulses due to scan time constraints. In this work, we applied a combined 3D dual echo Dixon and parallel imaging (PI) technique to patient breast imaging. We demonstrate that for the same scan parameters, the Dixon technique achieves an equivalent speed, superior SNR, and more uniform and complete FS when compared to the regular 3D technique combined with PI.
