Great care is taken during the set-up of multi-site
neuroimaging MR studies to ensure that data from
different scanners across different sites can be
combined appropriately. In practice there is a limit to
how similar imaging protocols can be. Here we take a
pragmatic, retrospective approach to investigate whether
protocol variations results in a measureable effect on
the anatomical brain images of a single subject scanned
multiple times on MR scanners from 2 manufacturers
installed at 3 sites. Very little differences were
found, suggesting that standardising multi-site
protocols may be less critical when combining data.
