We
applied super-resolution TDI, as a tool to gain spatial resolution
using post-processing methods, to one healthy individual to highlight
the fine details of the anatomical fibers tracts in the brainstem. A
1.25 mm isotropic diffusion data acquired in
vivo at 3T was used to
calculate a 0.2 mm isotropic TDI map. We demonstrated that the
super-resolution TDI clearly improved the spatial resolution, as well
as the emphasis on different contrast information. These maps can be
of help to anatomists to explore the brainstem complex organization
by identifying subject-specific tracts.
