We present the first multi-parameter maps of R1, R2* and effective proton-density (PD*) acquired at 400 ┬Ám isotropic resolution at 7T. Prospective motion correction (PMC) by external optical tracking was used to reduce motion artifacts, as well as to avoid a co-registration step during calculation of the maps. The maps allow for characterizing of subtle subcortical and cortical features such as the line of Gennari in the visual cortex.
