Fig. 5.

Brain volume in dilated 3D-T₁-weighted magnetic resonance images (T₁WI) compared with that in non-dilated 3D-T₁WI. Regions of significantly decreased volume (max cluster size is 103039 and max T value is 46.62 as true volume change within the lateral ventricles) are shown in the left panel, and regions of significantly increased volume (max cluster size is 530, max T value is 12.69 as the estimation error for the brain surface) are shown in the right panel. Significant volume differences are superimposed on the T₁ template image. The color bar (red to white) represents the T score. R and L indicate the right and left sides of the subjects, respectively.
