The developed duel-echo 3D-MERGE with adiabatic flow suppression can achieve improved image quality for large-coverage carotid vessel wall imaging. In addition, it can provide quantitative fat fraction and field maps for potential plaque component analysis.
Figure 2: Comparison of different 3D-MERGE scans on a volunteer (coronal view). (a) single-echo 3D-MERGE with composite hard pulse iMSDE and SPIR fat suppression. (b) single-echo 3D-MERGE with adiabatic iMSDE and SPIR fat suppression. Water (c) and fat (d) images as well as fat fraction (e) and field (f) maps are decomposed from dual-echo 3D-MERGE with adiabatic iMSDE. Note the signal intensity uniformity and fat suppression difference in those red arrow pointed regions in (a)-(c).

(b) single-echo 3D-MERGE with adiabatic iMSDE and SPIR fat suppression. Water (c) and fat (d) images as well as fat fraction (e) and field (f) maps are decomposed from dual-echo 3D-MERGE with adiabatic iMSDE. Note the signal intensity uniformity and fat suppression difference in those red circle regions in (a)-(c).
