Much work has gone into making diffusion weighted
imaging faster and more SNR efficient. Methods to
achieve this have included using multi-shot for reduced
distortions, 3D excitations for improved SNR efficiency,
and simultaneous multi-slice for higher acceleration
factors. In this work we combine all of this techniques
and introduce a pulse sequence with 3D navigator that
enables efficient acquisition of data capable of
combining all these techniques. The addition of a
blipped spiral-in navigator combined with a spiral
readout, allows for a time efficient way to collect
diffusion data and produces high quality diffusion
weighted images.
