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

Individual mixed cortical and deep grey 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.本数据集包含针对单扫描会话内可重复性的个体皮层与深部灰质混合感兴趣区测量数据，这些数据分别取自26名和22名受试者的首次与第二次成像扫描；同时还包含在两次扫描均完成的22名受试者中获取的跨扫描会话可重复性数据。展示的数据为各向异性分数（FA）、表观扩散系数（ADC）、轴向扩散系数（AD）及径向扩散系数（RD）测量值的变异系数百分比。
