MR-STAT is a framework for simultaneous mapping of quantitative MR parameters from a single short scan. Since MR-STAT involves the solution of a large scale nonlinear optimization problem, the reconstruction time has always been one main concern. In the current work, we develop an accelerated MR-STAT algorithm, which achieves two order of magnitude acceleration in reconstruction times. High-resolution 2D dataset can be reconstructed within 10 minutes on a desktop PC thereby drastically facilitating the application of MR-STAT in the clinical work-flow.
