The Double Echo Steady State (DESS) sequence has been
shown to provide diffusion weighted breast images
without the severe distortion of EPI DWI. However, DESS
images in the breast demonstrate prominent ghosting
artifacts, which, in the low SNR second echo can
compromise image quality. We investigated respiration
induced B0 in the breasts as the source of this artifact
and present initial results of correction of the
artifact using a DC navigator.
