A 3D whole brain T1, T2, T2*, QSM mapping pipeline was proposed for fast multi-parametric quantitative imaging. A multi-echo gradient echo (mGRE) sequence with varying sampling patterns along echoes was implemented to acquire signals for T2* and QSM mapping. A multi-contrast MR fingerprinting (MRF) sequence with both inversion recovery and T2 preparation pulses and varying sampling patterns among contrasts was implemented to acquire signals for T1 and T2 mapping. A deep ADMM network was used to reconstruct mGRE images. The magnitude image from reconstructed mGRE images was used to guide the reconstruction of MRF images with directional joint TV regularization.
