Fig. 3From: Optical imaging of pre-invasive breast cancer with a combination of VHHs targeting CAIX and HER2 increases contrast and facilitates tumour characterizationRapid increase of T/B ratio in the first 6 h p.i. allows fast imaging upon injection of the following: a B9-800 and 11A4-680 (n = 8), b 11A4-800 and R2-700 (n = 8) and c B9-800 and R2-700 (n = 7). Graphs represent mean ± SEM. At 6 h p.i, the p values were determined and statistical significance is indicated by * when p < 0.05 and *** when p < 0.0001Back to article page
