Figure 7: Effect of magnetic targeting on dose recovered from tumour in vivo. Mean dose calculated from fluorescence measurements is shown from 3 tumour samples for each condition (magnetic microbubbles (MMB), depleted (24 hour old) MMB, MMB + magnet and SonoVue). Error bars represent standard deviation. Asterisks represent statistical significance assessed using 1-way ANOVA followed by Tukey multiple comparisons test (**p < 0.01; ***p < 0.001; comparisons not shown have p < 0.0001).
