Figure 3.

Percentage difference in measured volumes compared to the measured volume. Percentage difference in measured volumes compared to the measured volume derived from SUV and Patlak images for various delineation methods applied to (A, B) NSCLC and (C, D) GI cancer. Note that some data points (for VOI⁵⁰ and Grad^WT2) fall outside the range of the figure. The percentage difference was defined as $\left(\frac{\mathsf{\text{Volum}}{\mathsf{\text{e}}}_{\mathsf{\text{SUV}}}}{\mathsf{\text{Volum}}{\mathsf{\text{e}}}_{\mathsf{\text{Patlak}}}}\mathsf{\text{ - }}1\right)\times 100\%$.
