Examples of acquiring PET parameters at the two different thresholds. This patient had mucinous BOT. PET parameters were measured within a VOI placed on the tumor. SUV thresholds were set at 1.5 (a) and 50 % of SUV_max (b). With a fixed SUV threshold of 1.5, MTV and TLG were 322.6 cm³ and 783.9 cm³ (a). With a threshold with 50 % of SUV_max, MTV and TLG were 85.2 cm³ and 291.2 cm³
