Agreement between each label in the cortical surface parcellations, generated via surface-based registration to an atlas space, from the MI-EPI-based and conventional MP-RAGE-based surface reconstructions. Dice coefficients computed for each of the 34 surface labels of the FreeSurfer “Desikan-Killiany atlas”, aparc, averaged across both hemispheres in one subject, quantifying the overlap or intersection of the sets of surface vertices contained within corresponding labels computed automatically from the MI-EPI-based and MP-RAGE-based surface reconstructions. Higher coefficient values indicate greater overlap (i.e., better agreement) between corresponding parcels. The high degree of overlap demonstrates that the labels derived from the MI-EPI-based surfaces are consistent with those estimated from the conventional MP-RAGE-based surfaces.
