This work presents a volumetric acquisition technique for fast fMRI using spirals and parallel imaging. Gradient blips were added along the readout of a stack of spirals sequence to produce a blipped stack of spirals for a more efficient sampling scheme. Phantom images and human fMRI experiments show that the method is capable of providing approximately a factor of two speed increase compared to a standard volumetric stack of spirals.
