In this work, a dual-echo 3D-MERGE with adiabatic flow suppression was developed to improve the image quality of large-coverage carotid vessel wall imaging (VWI). The initial experiments on plaque specimen and healthy volunteers have demonstrated its potential for plaque component analysis and feasibility to achieve isotropic 0.8mm VWI with improved fat/flow suppression and additional quantitative fat fraction/field maps by using this ~4min large-coverage scan.
