近年来，磁共振成像（MRI）已被广泛应用于研究健康和疾病的人体大脑的结构和功能。然而，有越来越多的关注重测信度的结构和功能的测量来自MRI数据。在这里，我们提出了一个重测数据集的多模态MRI，包括结构MRI（S-MRI），扩散MRI（D-MRI）和静息态功能MRI（R-fMRI）。招募了57名健康年轻人（年龄范围：19-30岁），并以大约6周的间隔完成了两次多模式MRI扫描。每个扫描会话包括R-fMRI、S-MRI和D-MRI数据。此外，在第一次会议开始和结束时有两次单独的R-fMRI扫描（间隔约20分钟）。这种多模态MRI数据集不仅提供了很好的机会，以调查在区域，连接和网络水平的大脑的结构和功能测量的短期和长期的重测可靠性，但也允许探测结构-功能耦合在人脑的重测可靠性。
Recently, magnetic resonance imaging (MRI) has been widely used to investigate the structures and functions of the human brain in health and disease in vivo. However, there are growing concerns about the test-retest reliability of structural and functional measurements derived from MRI data. Here, we present a test-retest dataset of multi-modal MRI including structural MRI (S-MRI), diffusion MRI (D-MRI) and resting-state functional MRI (R-fMRI). Fifty-seven healthy young adults (age range: 19–30 years) were recruited and completed two multi-modal MRI scan sessions at an interval of approximately 6 weeks. Each scan session included R-fMRI, S-MRI and D-MRI data. Additionally, there were two separated R-fMRI scans at the beginning and at the end of the first session (approximately 20 min apart). This multi-modal MRI dataset not only provides excellent opportunities to investigate the short- and long-term test-retest reliability of the brain’s structural and functional measurements at the regional, connectional and network levels, but also allows probing the test-retest reliability of structural-functional couplings in the human brain.
