Figure 3

In vivo mechanism of 125 I-cRGD-GNPs. (A) SPECT/CT images of tumor-bearing mice at 1, 2, and 4 h post injection; tumor tissues were circled and T/NT values were marked. (B) Changes of %ID/g of metabolins from the kidney and intestine. (C) Concentration change of radiosensitizer in the blood. (D) In vivo retained amount of targeted radiosensitizer reflected by retained radioactivity.
