Webenergy metabolism might be intermittently compromised within the ischemic penumbra. If the ischemic penumbra is characterized by these approaches, then a reduction of CBF to levels between a lower threshold of 10–15 mL/100 g/min and an upper threshold of approximately 25 mL/100 g/min is likely to identify penumbral tissue.
