The traveling heads 2.0: Multicenter reproducibility of quantitative imaging methods at 7 Tesla

This study evaluates inter-site and intra-site reproducibility at ten different 7 T sites for quantitative brain imaging.Two subjects - termed the "traveling heads" - were imaged at ten different 7 T sites with a harmonized quantitative brain MR imaging protocol. In conjunction with the system calibration, MP2RAGE, QSM, CEST and multi-parametric mapping/relaxometry were examined.Quantitative measurements with MP2RAGE showed very high...
