Multicontrast quantitative MRI is used to characterize left-right and sulcal-gyral asymmetries of the brain in 26 volunteers. Several regions with significant asymmetries are found in different parameters (H2O, fbound, R2*, R1, kex, QSM). Good correlation between sulcal-gyral H2O-defined asymmetry and local gyrification index is found.
