In low grade glioma (LGG), tumor vessels are mainly composed of normal endothelial cells (ECs), with cell-to-cell tight junction and relatively intact blood brain barrier (BBB) .
It could quantify the extent of tumor heterogeneity and discriminate oligodendroglioma from LGG [41-43].
 found the potential of rCBV for predicting IDH mutation status in LGG and anaplastic glioma.
All the parameters in LGG, HGG, and metastasis were lower, intermediate, and higher, respectively.

Awake surgery is considered the golden standard treatment for low-grade gliomas (LGG) in eloquent regions to optimize tumor resection while preserving neurological and cognitive functions and hence quality of life [1, 2].
Pathological examination of tumor tissue obtained during resection revealed a LGG (WHO grade II) in P1 and P3 and a HGG in P2 (WHO grade IV) and in P4 (WHO grade III).
However, results in P3 and P4 do not concur with this hypothesis: P3 with a LGG presented disturbances of memory, attention, and executive functions whereas P4 with a HGG demonstrated overall intact cognitive performance.
Currently, there is only evidence that a more extensive resection is associated with longer survival in both LGG and HGG patients .
