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.阿姆斯特丹超高场成人生命周期数据库（AHEAD）包含105例7特斯拉（T）全脑结构磁共振成像（MRI）扫描，该数据集专门针对人类皮层下成像优化，涵盖男女受试者，覆盖完整成人生命周期（19至80岁）。数据采用单次多回波磁化准备快速梯度回波（MP2RAGEME）序列以亚毫米分辨率采集，最终获得定量R1图谱、R2*图谱、T1图谱、T1加权图像、T2*图谱以及定量磁化率成像（QSM）的完整解剖配准结果。研究团队同时为五个独立的基底神经节结构生成了概率图谱。
