Analysis of brain connectivity using functional MRI and diffusion-weighted imaging

为了使用弥散加权成像和静息状态功能MRI对人脑的结构和功能连接进行可靠的分析，我们首先分析了扫描仪间和扫描仪内的变异性、纵向稳定性、扫描仪升级效应等，并显示了它们对大脑连接分析的影响。基于这些结果，我们研究了使用弥散加权成像和静息状态功能MRI分析脑连接的方法，将其应用于正常受试者获得的数据，并确认了方法的有效性。

For reliable analysis of structural and functional connectivity of the human brain using diffusion-weighted imaging and resting state functional MRI, we first analyzed inter-scanner and intra-scanner variability, longitudinal stability, scanner upgrade effects, etc. and showed their effects on brain connectivity analysis. Based on these results, we examined methods of analysis of brain connectivity using diffusion-weighted imaging and resting state functional MRI, applied them to data obtained on normal subjects, and confirmed the validity of the methods.
