The apparent diffusion coefficient (ADC) is elevated and
fractional anisotropy (FA) is reduced in age-related
white matter changes (WMC) regions has been reported.
This study is to determine the FA, relative anisotropy
(RA), volume ration (VR) and ADC in the regions of WMC
and the adjacent white matter tissue. A voxel expanded
label map was created to detect the change of adjacent
white matter tissue of the WMC regions. The FA, RA, VR
and ADC shows progressively change as the region
expands.
