(a) Comparison of the Akaike Information Criterion (AIC) for the delayed input function (AICDIF) and right heart input function (AICRHIF) models. Lower AIC values imply better description of the data for the number of model parameters. AICDIF was lower than AICRHIF (i.e., below the identity line) in 53 of 54 studied regions-of-interest. (b) Model improvement with the delayed input function, defined as the difference in AIC between the two models, was significantly correlated with the magnitude of ROI delays (tROI)
