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.
