In this study, an automated brain tissue segmentation method based on modeling of individual quantitative T1 values of brain tissues is proposed. To accomplish it, a fast T1 mapping using inversion recovery Look-Locker echo-planar imaging at a steady state (IR LL-EPI SS) with whole brain coverage is presented. This method is insensitive to instrumental settings and can be used to address specific patient populations and age-dependent groups.
