Multilevel Deficiency of White Matter Connectivity Networks in Alzheimer’s Disease: A Diffusion MRI Study with DTI and HARDI Models

Figure 7

Connectograms showing significantly different connections () based on the fiber counts between the AD group and the NC group, given (a) the DTI method and (b) the HARDI method. The thickness of each line indicates the extent of the difference between the corresponding connections in the two groups. The stronger connections (higher fiber counts between a pair of ROIs) in the AD group are shown in blue, while the weaker connections (lower fiber counts between a pair of ROIs) are in red. Refer to Table 2 for the label of each ROI.
