2 Mapping of the mean diffusion metrics over 17,646 subjects on the
cortex: fractional anisotropy (FA), mean kurtosis (MK), and axonal
water fraction (intra) from SMT MC model.
Figure
4. Brain age predictions using FA, MK, and SMT MC intra diffusion
metrics estimated over Desikan-Killiany atlas of cerebral cortex. The
predicted brain age values have been corrected for age bias. The
predictions were estimated using XGBoost algorithm for linear model
with sex and scanner site variables as covariance.
