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.
