Biodistributions of CPBs 2 and SPNPs 2. (a) 3D whole-body microPET images of the subcutaneous H22 tumor-bearing mice at different time points after tail-vein injection of the 18F-labeled CPBs 2 and SPNPs 2, respectively. (b) Rotational views of the 3D whole-body microPET images at 6 h after tail-vein injection of the 18F-labeled CPBs 2 and SPNPs 2, respectively. The dashed circles indicate the tumor regions. Movie files showing the complete 360° rotational views of the 3D whole-body microPET images of the subcutaneous H22 tumor-bearing mice at different time points after tail-vein injection of the 18F-labeled CPBs 2 and SPNPs 2 can be found in Movie S1 and S2, respectively. 3 mice were used for either CPBs 2 or SPNPs 2 in the microPET imaging.
