Isotropic T1-mapping of the whole brain by MP-RAGE at different inversion times

Helms, Gunther LU orcid and Olsson, Hampus LU (2021) ISMRM and SMRT Annual Meeting and Exhibition 2021 In Proc Intl Soc Magn Reson Med 29.
Abstract
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 anisotropic 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 andcompared to 3D IR-TSE and 3D variable flip angle mapping.
