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

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.
