The Amsterdam Ultra-high field adult lifespan database (AHEAD): A freely available multimodal 7 Tesla submillimeter magnetic resonance imaging database

The Amsterdam Ultra-high field adult lifespan database (AHEAD) consists of 105 7 Tesla (T) whole-brain structural MRI scans tailored specifically to imaging of the human subcortex, including both male and female participants and covering the entire adult life span (19-80 yrs). Data was acquired at a submillimeter resolution using a single multi-echo magnetization-prepared rapid gradient echo (MP2RAGEME) sequence, resulting in complete anatomical alignment of quantitative, R₁-maps, R₂^*-maps, T₁-maps, T₁-weighted images, T₂^*-maps, and quantitative susceptibility mapping (QSM). Probability maps were created for five individual basal ganglia structures.
