This study combined two recent innovations, track
density imaging (TDI) and multi-band diffusion
acquisitions, to create a clinically feasible 3-T MRI
protocol for thalamic parcellation to identify the
ventral intermediate nucleus (VIM) in elderly patients
with essential tremor prior to functional neurosurgery.
This represents a rapid translation of novel research
technology to clinical practice without requiring
high-field MRI or long scan times poorly tolerated by
real patients.
