Fig. 1.

Statistical maps of significant regions of texture differences between the subgroups. Two representative textures are shown (A: autocorrelation, Autoc; dissimilarity; Dissi). Areas of (+) higher texture value and (−) lower texture value when comparing the first to the second group are shown. Familywise error <0.05 and cluster size >30. Results are superimposed on MRI T1 templates for autoc (B, left) and dissi (B, right). Abbreviations: NC, normal controls; MCI, mild cognitive impairment; AD, Alzheimer's disease.
