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.
