The Spiral projection readout is combined with DW-SSFP
to acquire 3D diffusion weighted images at multiple diffusion directions in
reasonable scan times for whole brain coverage in a healthy human volunteer.
A retrospective cardiac gating technique and iterative-SENSE reconstruction
is used to address reproducible phase errors caused by cardiac motion and
compared to a standard gridding reconstruction. Images at multiple diffusion
encoding strengths are presented.
