In this work, we propose a novel motion corrected Phase Sensitive Inversion Recovery (PSIR) method with integrated T1 mapping derived from MP2RAGE acquisition. Motion correction is achieved using PROMO (PROspective MOtion correction), as well as Optimal Weighted Average (OWA) combination of multichannel data. This proposed method will be useful in obtaining high quality T1 images for children and other subjects who are prone to move during scans.
