A comparison of the biodistribution profile and the targeting properties of [99mTc]Tc-BQ0413 (40 pmol/mouse) with the 68Ga-labeled PSMA analog PSMA-11 (40 pmol/mouse) at 3 h pi (Figure 8) (details in Table A4 Appendix A) demonstrated that the tumor uptake of [99mTc]Tc-BQ0413 (30 ± 4 %IA/g) was significantly higher (p < 0.05, unpaired t-test) than the tumor uptake of [68Ga]Ga-PSMA-11 (20 ± 3 %IA/g). Here, FOLH1 is linked to neoplasm.
