 Abstract: Functional quantitative susceptibility mapping was performed on high resolution time-series acquired at 9.4T. Two alternative pulse sequences, two functional stimulation paradigms and three susceptibility mapping pipelines were evaluated. In addition to the conventional statistical parametric mapping of brain activation, also multivariate processing was performed in order to investigate the effect of physiological variations on the signal, and to learn about possible differences between these effects in the evolution of signal modulus and the evolution of calculated susceptibilities. The results provide useful information on the potential and the technical limitations of functional quantitative susceptibility mapping at 9.4T.
