Effect of scanner and head coil on diffusion MRI measures of the brain

The goal of this study was to compare diffusion parameters between three scanners of one vendor with the head-coils used in daily practice on the particular scanners. Of seven subjects, diffusion weighted MRI data were acquired on 3.0 Tesla Philips Intera, Achieva and Ingenia scanners. Signal to Noise Ratio (SNR), Mean Diffusivity (MD) and Fractional Anisotropy (FA) maps were compared. Inter-scanner differences were three times as large as intra-scanner differences. SNR varied up to 20% between scanners, was positively associated with MD and negatively with FA. Differences in MD and FA up to 7% are in agreement with literature.
