Using
a novel 15 channel coil for carotid artery imaging we could prove that the
g-factor loss at higher acceleration factors is limited. This permits the use
of higher parallel imaging factors than commonly exploited in carotid MRI. A 4D
flow scan at high spatiotemporal resolution was accelerated 10 fold (SENSE 4 x
2.5), resulting in high quality images and consistent flow values acquired in a
scantime as short as 7 min.
