Within and between session variability of diffusion tensor imaging region of interest measurements.

Individual white matter region of interest measurements for within session reproducibility obtained in the first and second imaging sessions in 26 and 22 subjects respectively, and the between session reproducibility for those 22 subjects who underwent imaging at both sessions. Data displayed are percentage coefficient of variation of measurements for fractional anisotropy (FA), apparent diffusion coefficient (ADC), axial (AD) and radial (RD) diffusivity.

本数据集包含针对26名受试者于首次成像扫描会话、22名受试者于第二次成像扫描会话中获取的会话内可重复性相关白质感兴趣区（white matter region of interest）测量值，以及同时完成两次成像扫描的22名受试者的会话间可重复性数据。所展示的数据为各向异性分数（fractional anisotropy，FA）、表观扩散系数（apparent diffusion coefficient，ADC）、轴向扩散系数（axial diffusivity，AD）与径向扩散系数（radial diffusivity，RD）的测量值的百分比变异系数。
