QRAGE is a novel imaging sequence and reconstruction method for the simultaneous mapping of multiple quantitative MRI parameters, including water content, T1, T2*, and magnetic susceptibility at ultrahigh field strength. QRAGE employs a novel ME-MPnRAGE sequence that acquires 171 contrast images at different inversion and echo time points, enabling accurate and precise parameter estimation. It further incorporates a novel model-based reconstruction method, MIRAGE2, that leverages prior knowledge of temporal signal evolution represented as damped complex exponentials by minimizing local Block-Hankel and Casorati matrices. Parameter maps are derived from the reconstructed contrast images through postprocessing steps.
