Figure 7From: Aptamer-modified magnetic nanoprobe for molecular MR imaging of VEGFR2 on angiogenic vasculatureIn vivo VEGFR2-targeting ability of Apt-MNC. (a) T 2-weighted MR images and their color map for VEGFR2-expressing mouse model with intravenous injection of Apt-MNC or carboxylated MNC (red line: brain tumor, red arrow: contrast enhanced site). (b) Signal intensity graphs from T 2-wieghted MR images (*p < 0.01).Back to article page
