For CENTER-TBI, a large European multi-center study on
Traumatic Brain Injury, diffusion tensor imaging (DTI)
is one of the main imaging modalities. 35 clinical sites
across Europe will be included to participate in the MRI
study. To be able to acquire DTI data that is cross-site
comparable it is of fundamental importance to assess the
quality and variability of DTI measurements across
sites. In this work 35 anisotropic phantoms were
produced and evaluated in order to construct a set of
baseline measurements. There is a considerable range of
FA values between phantoms, but this may be attributed
to post-processing and/or partial volume effects.
