Spectrally Selective Excitation for Improved DWI, APT and MRS of the Breast

Lipid suppression is an area where proven approaches in the brain often fail because of more heterogeneous water-fat distribution in the breast. Here, we present our initial experience combining spectrally selective excitation with DWI, APT and MRS in the breast. Our preliminary results demonstrated water only excitation as a feasible alternative to existing methods of fat suppression with a moderate increase in echo time.
