As shown in Figure 5 and Table 1, [177Lu]Lu-PSMA-Q showed the highest uptake in the tumor at 24 h p.i. (3.87 ± 0.32 ID%/g), which was similar to that of [177Lu]Lu-PSMA-617 (3.74 ± 0.29 ID%/g, p = 0.63), both of which were significantly higher than those of [177Lu]Lu-PSMA-BP (2.98 ± 0.21 ID%/g) and [177Lu]Lu-PSMA-4PY (2.61 ± 0.49 ID%/g) (p < 0.05). The gene discussed is FOLH1; the disease is neoplasm.
