TOF-MRA sometimes cannot delineate the vessel clearly depending on the vessel orientation. Additionally, insufficient fat suppression can occur in FS-T1-VISTA, it may obscure the plaque depiction. we have developed a new sequence, termed Phase-contrast ANgiography with Dark-blood Application (PANDA), which can simultaneously acquire bright-blood image (MRA) and vessel-wall images (VWI) using the phase contrast method. There was no difference in the visualization ability of carotid plaque between PANDA-VWI and FS T1 VISTA. PANDA-MRA better visualized around the aorta compared to TOF-MRA. PANDA is useful method for simultaneous acquisition of MRA and VWI images.
