Arcuate Faciculi

Group average FA and MD values are shown in the left and right arcuate faciculi in Figure 11.  In these non-motor tracts, there is no apparent difference in the FA averages in neither the left nor right arcuate faciculus . Mean diffusivity is greater in the AD group in approximately 80% of the tracts in each hemisphere . There is no apparent difference in FA in the left cingulum hippocampus, however in approximately 19% of the right cingulum hippocampal tract FA values are higher in the HC group. The AD group has higher MD values along approximately 25% of the left and 75% of the right cingulum hippocampal tract (Figure 12).
