Fractional anisotropy (FA) may depend not only on the
fiber orientation but also on the axonal density. In the
case of a white matter disease, a change in either fiber
orientation or axonal density will result a change in FA
value. The orientation dispersion index and
intra-cellular volume fraction, two tissue specific
measures from NODDI model, can be used to study changes
in fiber orientation and axonal density. In this study,
aging data collected using a multiple shell acquisition
scheme (HYDI) was analyzed using FA, odi and icvf to see
how age and gender affect in these measures.
