The “traveling heads” is a study to assess the comparability and reproducibility of multicenter human brain imaging at 7T. In previous experiments, we compared typical UHF sequences for structural brain imaging. In this study, we focus on the reproducibility of quantitative imaging and compare methods for volumetry, relaxometry, QSM and CEST between different sites. In addition, three generations of 7T MR systems are compared, i.e. the older installed base consisting of passively and actively shielded magnets of the first and second generation, respectively, as well as the most recent generation which has been approved as a medical device.
