It
is important that the region of interest (ROI) has enough repeatability
especially for serial measurement. We developed the novel algorithm and
software GAMA using diffusion tensor imaging. The GAMA can point out the
regions as corpus callosum or pyramidal tract automatically. Therefore, we can
use GAMA with very brief handling. Additionally, GAMA could evaluate FA in
that region with higher reproducibility than the conventional ROI methods
with the free-handed ROI or the size-fixed sphere ROI.
