In a recent paper Liu and Li presented a novel MR
phase-based technique to assess tissue anisotropy, in
the following referred to as (multipole) Fourier
spectrum Tensor Imaging (FTI). In this contribution we
show that the microstructural anisotropy measured by FTI,
though being derived from the MR phase, does neither
specifically reflect magnetic susceptibility anisotropy
(as STI does; e.g. due to myelin) nor does it require an
anisotropic distribution of magnetic susceptibility
inclusions at all.
