Fitting the inversion recovery (IR) at multiple TI provides T1 estimates of high accuracy if performed in a single slice with full relaxation. We present an isotropic 3D variant based on MP-RAGE, where a T1-weighted driven equilibrium is prepared prior to inversion by a second RAGE readout. This abolishes the need for long recovery times and provides volumes of similar contrast for co-registration. The method was tested at 3T on a small cohort and compared to 3D IR-TSE and 3D variable flip angle mapping.
