Figure 6: Quantitative tissue biodistribution of Au and Gd in HCC-LM3-fLuc subcutaneous tumor-bearing mice after intravenous injection: 2 h (a), 5 h (b), and 12 h (c). Data was presented as mean ± SD (), , significant difference compared with the other tissue distribution of Au and Gd; (d) the correlation between concentrations of Au and Gd.
