Mean percent error on the estimate of MTV of small lesions as a function of L/B_m, for the adaptive and fixed threshold segmentation methods.

L/Bm	Adaptive threshold mean percent error (%)	Fixed threshold mean percent error (%)
L/Bm ≤ 5	27 ± 9	−33 ± 13
5 < L/Bm ≤ 10	16 ± 30	−35 ± 26
10 < L/Bm ≤ 15	17 ± 16	−31 ± 25
