Simultaneous Multislice (SMS) imaging, also termed "Multiband" (MB), was integrated into slab-selective 4D flow MRI to quantify blood hemodynamics simultaneously in both carotid bifurcations at 7T. Therefore, sagittal oriented MB 4D flow acquisitions with 0.8mm isotropic resolution were performed in 4 volunteers using a dedicated carotid coil. The same protocol was then repeated twice, but only a single slab ("SingleBand" - SB) targeting the left or right carotid bifurcation was excited. Peak velocity and net flow quantification was performed for reconstructed MB and SB data on 3 planes each, one before and two after the bifurcation.
