Arterial spin labeling (ASL) can be used to study stroke
and other cerebrovascular diseases. Biexpoential fit to
the signal decay data arising from the vascular and
tissue compartments acquired using a modified diffusion
weighted (DW) - ASL perfusion technique yields the fast
and slow diffusion components and their respective
volume fractions. In this study, we demonstrated the
differences in the fitted parameter in both the slow and
fast diffusing components in the white and gray matter
in non-human brain primates using diffusion weighted (DW)
- ASL perfusion data.
