This work studies cross-site variability in 7 Tesla task fMRI measurements, collected as part of a “travelling heads” study. Participants were scanned at the five human UK 7 Tesla MRI sites, and results are presented from four of these sites. A motor-visual task was performed at each site with acquisitions matched as closely as possible. Despite some apparent differences in tSNR , we demonstrate that it is possible to achieve good agreement across sites. The %BOLD coefficient of variation of 0.1-0.2 across sites was similar to the within-site ranges. This work sets the foundation for multi-site 7 Tesla clinical trials.
