The aim of this study was to assess the effect of the lipids on the quantification of IVIM parameters in the vertebral bone marrow. Diffusion sequences were acquired with and without fat suppression on healthy volunteers. The results of our study show that fat is a confounding factor for the quantification of the diffusion coefficient and perfusion fraction; whereas it has no significant effect on the quantification of the pseudo-diffusion coefficient.
