This abstract presents a CAIPIRINHA style sampling using
a 3D stack-of-spiral trajectory. By rotating the spiral
interleaves along the through-plane direction, the
encoding capability of the receiver sensitivities can be
better used to improve the g-factor. We show the
improved quality of the 3T in vivo human brain images
acquired at 2
using this method. In addition, this abstract presents a
3D GRAPPA method that is used to reconstruct the
CAIPIRINHA style under-sampled stack-of-spiral data.
