Parallel Imaging techniques have not been introduced for Gradient and Spin Echo sequences being a limiting factor for clinical use. Enabling PI for GRASE requires new view-ordering schemes that acquire an autocalibration region while simultaneously mitigating artifacts and obtaining the desired contrast. The purpose of this work is to present new 2D PI accelerated Cartesian view-ordering schemes with either T2 or PD contrast in multi-shot VFA 3D-GRASE, for relevant SAR and scan time reduction compared to 3D-FSE/TSE.
