- FIGURE 1.
Example of manual quantification for one patient, with mFTV10 corresponding to sum of all VOIs (81.38 mL) and mTLF10 corresponding to mFTV10 multiplied by average of all SUVmax (1,266.27 g).
- FIGURE 2.
(A) After threshold selection (SUVmax of 10), several VOIs are automatically created. (B) On visual inspection, VOIs not related to metastases are deleted. In this patient, as indicated by white arrow in coronal section on CT scan, uptake was noted in calcified portion of liver, which was a sequela of radioablation (L11VOI1); this lesion was manually excluded. (C) Patient’s final saTLF10 was 3,969 g.

Graph showing strong correlation between values for mTLF10 and mFTV10 (ρ = 0.8117; P < 0.0001; 95% confidence interval, 0.6905–0.8885).
- FIGURE 4.
Graph showing strong correlation between values for saTLF10 and saFTV10 (ρ = 0.9234; P < 0.0001; 95% confidence interval, 0.8690–0.9558).
- FIGURE 5.
Bland–Altman test showing similarity between manual and semiautomatic quantifications.
- FIGURE 6.
Mountain plot showing similarity between manual and semiautomatic quantifications, with peak near zero and small left tail.
