Voxel-wise scatter plot for \({K}_{1}\) (a), \({k}_{2}\) (b), and \({k}_{3}\) (c) for the six subjects from the validation cohort (P7–P12) showing the coefficient of determination (\({R}^{2}\)) and linear regression analysis for the correlation between the parametric maps estimated using the descending aorta IDIF (\({IDIF}_{DA}\)) and the automatically extracted image-derived input function from brain images (\({IDIF}_{Auto}\))
