On the left hand side, ROC curves regarding prediction of FIV (group (A)) using ATI. On the right hand side, optimal threshold distribution per subject in seconds regarding Tmax of ATI using Dice’s coefficient and Youden-Index. CBV = cerebral blood volume. MTT = mean transit time. CBF = cerebral blood flow. Tmax = time to the maximum of the residue function obtained by deconvolution.
