Figure 5:

Box plots show radioactivity measurements that enabled us to confirm the findings of mouse fluorescence imaging studies. At 3 hours after injection, the percentage of injected dose accumulated by SLNs in the low-dose group (0.11 nmol) accumulated a significantly (P = .007) greater percentage (0.40% ± 0.16) of the injected dose than did the high-dose group (31 nmol) (0.16% ± 0.08). SLN extraction in the low-dose group (83% ± 11) was greater (P = .042) than that in the high-dose group (54% ± 31).
