Average of CBF, CVR, and v in CGM. The unit of CBF, CVR, and v is ml/min/100g, Δ%CBF/mmHg PetCO2, and %, respectively. The baseline CBF was acquired in DGCB, then registered to QSM resolution. BL and HC indicate baseline and hypercapnia, respectively. The HC-CBF was inferred based on the cerebrovascular reactivity (CVR) from DGCB during hypercapnia and PetCO2 obtained from QSM during hypercapnia, respectively. BL-v and HC-v maps are shown in Supporting Information Figure S3.
