DTI has mainly been used to assess brain white matter fibers, but the potential to assess micro-structures at the tumor cell level is unexplored. DTI contains much information beyond FA and v1FA colormap that has not been well exploited to study tumor microstructure. We found the tensor shapes encoded colormaps can potentially allow the identification of a rim of planar tensors at the boundary of a tumor and extracted information contained within the tertiary eigenvector.
