Cerebral perfusion metrics calculated directly from a hypoxia-induced step change in deoxyhemoglobin

Abstract Resting cerebral perfusion metrics can be calculated from the MRI ΔR2* signal during the first passage of an intravascular bolus of a Gadolinium-based contrast agent (GBCA), or more recently, a transient hypoxia-induced change in the concentration of deoxyhemoglobin ([dOHb]). Conventional a...
