Template-based methods offer a reliable way to conduct
inter-subject studies. Building upon recent developments
of a spinal cord template, this study focuses on the
construction of an atlas of spinal white matter
pathways. Cross-sectional drawings of Grays anatomy
were manually segmented, then warped to the
MNI-POLY-AMU_v1 template using symmetric diffeomorphic
transformation. The atlas was then propagated between C1
and T1 vertebral levels, yielding 30 different regions
of interest, taking into account partial volume effect.
We demonstrate the utility of this atlas for quantifying
diffusion-tensor-imaging data in five healthy
volunteers. The method can be extrapolated to other
multiparametric techniques.
