(a) LIMCA_StO2 versus LIMCA_CBF, (b) LIMCA_StO2 versus LIMCA_CVR, (c) LIMCA_CMRO2 versus LIMCA_CBF, and (d) LIMCA_CMRO2 versus LIMCA_CVR (n = 12). StO2, tissular oxygen saturation; CBF, cerebral blood flow; CMRO2, cerebral metabolic rate of oxygen; CVR, cerebrovascular reserve; LIMCA, laterality indices in MCA territories. Each triangle, diamond and square represents patient with right (MCA/ICA), Left (MCA/ICA) or bilateral (MCA/ICA) stenosis, respectively.
