Fig. 7

Coronal views of ¹⁸F-FDG parametric images for a lymphoma patient (subject 6). The figure shows parameter maps of \(K_{1}\) (\({\text{ml}}/{\text{cm}}^{3} /{\text{min}}\)), \(k_{2}\) (\(1/{\text{min}}\)), \(k_{3}\) (\(1/{\text{min}}\)), and \(K_{i}\) (\({\text{ml}}/{\text{cm}}^{3} /{\text{min}}\)), obtained using AIF extracted from the descending aorta (\(IDIF_{DA}\)) and brain with an automated framework (\(IDIF_{Auto}\)). The AIF errors between the two methods were \(AUC_{error}\)=1.02% and NRMSE = 0.11
