The Pointwise Comparison of FA Profiles among AD, MCI, and NC groups from our cohort.

The plots of the FA profiles of 20 tracts from AD patients (red), MCI patients (green) and NC subjects (blue) as means (SD) (solid lines for means and shaded areas for SDs). The color bars under the FA profiles indicate the regions of significant difference between AD and NC (red), MCI and NC (green), and between MCI and AD (blue). The X-axis represents the location between the beginning and termination waypoint regions of interest. Abbreviations in context: ATR, anterior thalamic; CST, corticospinal tract; CCing, cingulum cingulate; CHippo, cingulum hippocampus; CC, corpus callosum; IFOF, inferior fronto-occipital fasciculus; ILF, inferior longitudinal fasciculus; SLF, superior longitudinal fasciculus; UF, uncinated fasciculus. AF, arcuate fasciculus. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
