The reproducibility of diffusion MRI parameters, and more specifically the apparent diffusion coefficient (ADC), intra-voxel incoherent motion (IVIM) parameters the diffusion coefficient (D) and perfusion fraction (f), and diffusion tensor imaging (DTI) parameters mean diffusivity (MD) and fractional anisotropy (FA), was analysed across multiple centres using standard clinical protocols. ADC, D, MD and FA were found to have a good reproducibility and research studies can benefit from incorporating multi-centre data without any loss of reproducibility compared to what would be achieved from a single scanner at a single site.
