By adding long TEs to the Dixon acquisition, the chemical-shift-based T2*-weighted multi-echo GRE (CS-T2*-mGRE) techniques have gained attention, because they are able to generate co-registered multi-contrast images and quantitative maps. However, flow-suppressed CS-T2*-mGRE sequences have not been evaluated for carotid wall imaging. We compared the performance of simultaneous quantification of fat fraction (FF) and R2* from CS-T2*-mGRE sequences with and without saturation slabs, and with the incorporation of DANTE pulses for black blood imaging (DANTE-CS-T2*-mGRE); we used the FF for fat-suppression to better visualize the vessel wall from DANTE-CS-T2*-mGRE as well as the carotid artery lumen from CS-T2*-mGRE.
