Inter-session statistics.

Mean and ΔCBF represent the inter-session CBF mean and paired difference respectively.The limits of agreement (LOA) represent ΔCBF±1.96 standard deviation of the paired difference (SDΔCBF).CI = confidence interval, CBF = cerebral blood flow, GE = General Electric, GM = gray matter,WM = white matter, wsCV = within-subject coefficient of variation.均值（Mean）与ΔCBF分别代表会话间脑血流量（cerebral blood flow, CBF）的均值以及配对差值。一致性界限（limits of agreement, LOA）的定义为ΔCBF±1.96倍配对差值的标准差（SDΔCBF）。其中CI为置信区间（confidence interval），CBF为脑血流量，GE为通用电气（General Electric），GM为灰质（gray matter），WM为白质（white matter），wsCV为受试者内变异系数（within-subject coefficient of variation）。
