Visualizing intrathalamic structures anatomically is
important for guidance of surgical interventions, as
well as validating existing thalamic parcellations from
functional connectivity or DTI tractography, though it
has proven quite difficult. Recent reports have begun to
identify methods capable of identifying these structures
via susceptibility weighted imaging, or by visualizing
white matter boundaries between these structures using
optimized MPRAGE acquisitions. We present evidence of
the potential for the combined use of these techniques
to increase the structures that can identified on an
individual level. Furthermore, we demonstrate the
utility of imaging with MPRAGE imaging with shorter
inerversion delays for intrathalamic parcellation.
