Fig. 4From: Automated extraction of the arterial input function from brain images for parametric PET studiesDisplays a comparison between the arterial input function automatically extracted from brain images (\({IDIF}_{Auto}\)) and the descending aorta IDIF (\({IDIF}_{DA}\)) for the six subjects from the validation cohort (P7–P12). The \({IDIF}_{Auto}\) is represented by the purple dashed line, and the \({IDIF}_{DA}\) is shown as the red dashed-dotted lineBack to article page
