Here, we present an extension to our previously published structural ultrahigh resolution T-weighted magnetic resonance imaging (MRI) dataset with an isotropic resolution of 250 µm, consisting of multiple additional ultrahigh resolution contrasts. Included are up to 150 µm Time-of-Flight angiography, an updated 250 µm structural T-weighted reconstruction, 330 µm quantitative susceptibility mapping, up to 450 µm structural T-weighted imaging, 700 µm T-weighted back-to-back scans, 800 µm diffusion tensor imaging, one hour continuous resting-state functional MRI with an isotropic spatial resolution of 1.8 mm as well as more than 120 other structural T-weighted volumes together with multiple corresponding proton density weighted acquisitions collected over ten years. All data are from the same participant and were acquired on the same 7 T scanner. The repository contains the unprocessed data as well as (pre-)processing results. The data were acquired in multiple studies with individual goals. This is a unique and comprehensive collection comprising a "human phantom" dataset. Therefore, we compiled, processed, and structured the data, making them publicly available for further investigation.
在这里,我们展示了之前发布的具有 250µm 各向同性分辨率的结构超高分辨率 T 加权磁共振成像 (MRI) 数据集的扩展,其中包含多个额外的超高分辨率对比度。其中包括多达 150µm 的时飞 (TOF) 血管造影术、更新的 250µm 结构 T 加权重建、330µm 定量磁化率映射、多达 450µm 的结构 T 加权成像、700µm T 加权背靠背扫描、800µm 扩散张量成像、具有 1.8mm 各向同性空间分辨率的 1 小时连续静息态功能 MRI 以及超过 120 个其他结构 T 加权容积,以及十多年来收集的多个相应的质子密度加权采集。所有数据均来自同一参与者,且均在同一台 7T 扫描仪上采集。存储库包含未处理的数据以及(预处理)结果。这些数据是在多个具有不同目标的研究中采集的。这是一个独特而全面的数据集,包含一个“人体模型”数据集。因此,我们对数据进行了编译、处理和结构化,使其可供进一步研究。
