Table 2.
Six examples that each showed in a single lesion highest impact in relative difference of SUVmax between the standard 4-compartment and improved 5-compartment, respectively 6-compartment μ-map. Note that the highest relative increase in SUVmax with 28.4% could be observed in the thoracic spine (lesion no. 4). The second highest relative increase in SUVmax with 22.3% was observed in the os sacrum (lesion no. 3) of another patient. In these two examples, the relative impact of HUGE truncation correction on lesion SUVmax was higher than the relative impact of adding bone information (diff. 4-comp. vs. 5-comp.) to the μ-map
