abstract = {Conventional diffusion‐weighted (DW) MRI suffers from
free water contamination due to the finite voxel size. The
most common case of free water contamination occurs with
cerebrospinal fluid (CSF) in voxels located at the
CSF‐tissue interface, such as at the ventricles in the
human brain. Another case refers to intra‐tissue free
water as in vasogenic oedema. In order to avoid the bias in
diffusion metrics, several multi‐compartment methods have
been introduced, which explicitly model the presence of a
free water compartment. However, fitting multi‐compartment
models in DW MRI represents a well known ill conditioned
problem. Although during the last decade great effort has
been devoted to mitigating this estimation problem, the
research field remains active.The aim of this work is to
introduce the design, characterise the NMR properties and
demonstrate the use of two dedicated anisotropic diffusion
fibre phantoms, useful for the study of free water
elimination (FWE) and mapping models. In particular, we
investigate the recently proposed FWE diffusion tensor
imaging approach, which takes explicit account of
differences in the transverse relaxation times between the
free water and tissue compartments.},
