Fat suppression is essential in high-resolution DCE-MRI of the breast. While chemical shift selective excitation (i.e. ProSet) is sensitive to magnetic field distortions, Dixon techniques may be sensitive to T 2 * effects due to their multi echo acquisition (ME-Dixon), or to motion when applied as multi acquisition (MA-Dixon). In this study, we investigated the efficiency of these fat suppression techniques at ultra-high resolutions obtained at 7 tesla. In ten healthy volunteers ProSet revealed structural details that were not observed with Dixon. Despite a non-uniform fat suppression of ProSet, the technique remains superior in CNR and time efficiency over other techniques.
