Furthermore, the [68Ga]Ga-PSMA-617 BTV was approximately four times larger than the CE tumor volume (p = 0.004), suggesting that [68Ga]Ga-PSMA-617 might accumulate in regions of early neoangiogenesis that are yet to progress to a stage where they present blood–brain barrier leakage. The gene discussed is FOLH1; the disease is neoplasm.
