Diffusion tractography is the only method available to
study the brains white matter anatomy in-vivo, however,
it does not provide accurate information about the
terminations of white matter tracts. This poster
presents a method to extract white matter tract
terminations (ExTracT) using tractography, and
illustrates the method by performing the technique on
the temporal lobe. The results demonstrate that ExTracT
is capable of reliably identifying voxels near the
brains surface that contribute to a tract, enabling the
generation of tract termination maps. These termination
maps can be used to improve basic white matter
anatomical knowledge in health and disease.
