FOLH1 and neoplasm: It should be mentioned that there was a tendency toward decrease in tumor uptake in the blocking groups: 38 ± 6 %IA/g in the [99mTc]Tc-BQ0413 (40 pmol) group, 31 ± 4 %IA/g in the [99mTc]Tc-BQ0413 (40 pmol) + PSMA-11 (5 nmol) group, and 33 ± 3 %IA/g in the [99mTc]Tc-BQ0413 (40 pmol) + BQ0413 (5 nmol) group, but the difference was not significant.
