VEGFA and glioblastoma: Moreover, Awasthi R et al. found that relative cerebral blood volume and relative cerebral blood flow were significantly correlated with VEGF expression level [38]; Li K et al. reported that combining the radiomic features and VEGF expression level could predict pelvic lymphatic metastasis [34]; Yin Q et al. revealed the associations between tumor angiogenesis and radiomic imaging features from PET/MRI [35], and Beig N et al. analyzed the hypoxia pathway radiomic features and predicted the overall survival in GBM [36].
