For all 19 cases, the mean Vol-T2 was 32.93 cm3 (range, 3.3–106.60 cm3). The average summed volume Vol-(T2∪PET) was 36.36 cm3, and the average intersection Vol-(T2 ∩ PET) was 11.12 cm3. The average Vol-(T2 minus PET) was 21.78 cm3 (range, 0.8–83.20 cm3), and the average Vol-(PET minus T2) was 3.43 cm3 (range, 0–17.5 cm3).
