Forstmann<p>The <strong>A</strong>msterdam Ultra-<strong>h</strong>igh fi<strong>e</strong>ld <strong>a</strong>dult lifespan<strong> d</strong>atabase (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, R<sub>1</sub>-maps, R<sub>2</sub><sup>*</sup>-maps, T<sub>1</sub>-maps, T<sub>1</sub>-weighted images, T<sub>2</sub><sup>*</sup>-maps, and quantitative susceptibility mapping (QSM). Probability maps were created for five individual basal ganglia structures.</p>
