Figure 10From: Magnetic resonance imaging of glioma with novel APTS-coated superparamagnetic iron oxide nanoparticlesR 2 values of C6 glioma xenografts labeled with 25 μ g/mL Fe 3 O 4 NPs at 7, 14, 21, and 28 days. The R2 value of C6 glioma xenografts that were treated with PBS buffer after 14 days was used as a control value.Back to article page
