The Amsterdam Ultra-high field adult lifespan database (AHEAD): A freely available multimodal 7 Tesla submillimeter magnetic resonance imaging database
收藏资源简介：
The <b>A</b>msterdam Ultra-<b>h</b>igh fi<b>e</b>ld <b>a</b>dult lifespan<b> d</b>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.
