3D coverage of the whole
brain by using RARE-refocused stack-of-2D-spirals often suffers from low
temporal/spatial resolution due to the long spiral readout or long echo train.
In this work we present a method that allows whole-brain coverage at 3 mm
isotropic spatial resolution with one- or two-segment, accelerated acquisitions
in both partition and spiral directions. The technique was applied in
conjunction with background-suppressed pCASL, resulting in improved
temporal/spatial resolution for quantification of cerebral blood flow.
