In this work we present quantitative T1-maps obtained using the silent, zero echo-time, RUFIS sequence at 7T. Four flip angles (2,4,8,11)° were acquired in 5 minutes. The obtained T1-maps showed strong contrast between white matter (T1=1.6s) and cortical grey matter (T1=2.3s), in agreement with values in the literature. Reduced contrast was observed in deep grey matter structures, attributed to large B1+-errors in the centre of the brain.
