      abstract     = {Artificial, anisotropic fibre phantoms are nowadays
                      increasingly used in the field of diffusion-weighted MRI.
                      Such phantoms represent useful tools for, among others, the
                      calibration of pulse sequences and validation of diffusion
                      models since they can mimic well-known structural features
                      of brain tissue on the one hand, but exhibit a reduced
                      complexity, on the other. Among all materials, polyethylene
                      fibres have been widely used due to their excellent
                      properties regarding the restriction of water diffusion and
                      surface relaxation properties. Yet the magnetic
                      susceptibility of polyethylene can be distinctly lower than
                      that of distilled water. This difference produces strong
                      microscopic, background field gradients in the vicinity of
                      fibre bundles which are not parallel to the static magnetic
                      field. This, in turn, modulates the MRI signal behaviour. In
                      the present work we investigate an approach to reduce the
                      susceptibility-induced background gradients via reducing the
                      heterogeneity in the internal magnetic susceptibility. An
                      aqueous solution of magnesium chloride hexahydrate
                      (MgCl2·6H2O) is used for this purpose. Its performance is
                      demonstrated in dedicated anisotropic fibre phantoms with
                      different geometrical configurations.},
