Besides their usual methodological use to characterize the NMR characteristics of specific chemical drugs, T1, T2 or T2* mapping is now progressively used in neuro-scientific studies, for instance to better understand the structural modifications occurring during brain development. Despite major improvements using DESPOT1 and DESPOT2 pulse sequences, mapping the whole brain relaxometry still requires scan durations not always compatible with clinical use. In this abstract, we present a novel solution dedicated to perforrm rho, T1, T2, and T2* mapping of the human brain in real-time with a low scan duration and a 1.5mm isotropic resolution.
