A number of recent studies in nuclear medicine imaging not only confirmed the high expression of PSMA in GBM relative to normal brain tissues or low-grade GBM tissues, but also showed that, through 68Ga-PSMA or PSMA antibody loaded 89Zn- Df-IAB2M, the PET/CT imaging possessed the ability to visualize the neovascularization of GBM and guide the targeted therapy of GBM (Schwenck et al., 2015; Kunikowska et al., 2018; Matsuda et al., 2018). Here, FOLH1 is linked to glioblastoma.
