(A) Perfusion curves calculated within regions of low and high MTRasym (shown in blue and red colors, respectively), suggesting poor discrimination of the regions solely based on hemodynamic curves. (B) Discrimination of low and high MTRasym regions based on PC analysis; PC1 = principal component 1; PC2 = principal component 2; PC3 = principal component 3. (C) The three principal components for high MTRasym regions, yielding a marked differentiation of these regions based on the PCs.
