This work presents a new feasibility to extract tissue susceptibility from gradient-echo MRE data and enables simultaneous QSM and MRE in a single scan. The proposed method builds on a new spiral staircase acquisition which enables high resolution often required by QSM using inherently improved through-plane parallel imaging. In-plane parallel imaging, constrained reconstruction and deblurring method are also integrated to generate high quality spiral images for QSM and MRE processing. In vivo experiment results demonstrate the capability of proposed method in producing high quality tissue susceptibility along with shear stiffness maps from a single 5-minute scan.
