Isotropic High-Resolution 3D Diffusion Weighted SSFP Imaging with Spiral Projection Imaging

Rafael Luis O'Halloran¹, Murat Aksoy¹, Eun Soo Choi¹, Roland Bammer¹

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.
