Data-driven optimized flip angle selection for T(1) estimation from spoiled gradient echo acquisitions

PURPOSE: Define criteria for selection of optimal flip angle sets for T(1) estimation and evaluate effects on T(1) mapping. THEORY AND METHODS: Flip angle sets for SPGR-based T(1) mapping were selected by minimizing T(1) estimate variance weighted by the joint density of M(0) and T(1) in an initial...
