MR parameter mapping has shown great potential but is still limited in clinical application due to the lengthy acquisition time. To address this issue, we proposed a novel image reconstruction method(PARMA) to accelerate parameter mapping with reduced multi-channel acquisition using alternating projections on the single-exponential parametric manifold, the subspace data consistancy, and the convex of the regularized coil sensitivities. The experimental results show the potential of highly accelerated quantitative imaging by the proposed method.
