Figure 4 Normalized relative cerebral blood volume ratio (nCBV) vs normalized cerebrovascular reactivity ratio (nCVR) (A) and normalized relative cerebral blood flow ratio (nCBF) vs normalized CVR ratio (nCVR) (B) in our cohort of low grade gliomas. As described in the Methods section, these normalized ratios were calculated by dividing the mean voxel values obtained in ipsilesional regions of interest (ROIs) by those obtained in mirror contralesional ROIs. Neither nCBF nor nCBV demonstrated significant inverse correlation with nCVR in this LGG group. LGG: Low grade gliomas; CVR: Cerebrovascular reactivity
