Knowledge of CBF in neonates or infants may provide valuable information in many pathological conditions. When applied to very young children, CBF mapping using arterial-spin-labeling (ASL) MRI suffers from low SNR and poor quantification, whereas phase-contrast (PC) MRI may provide reliable estimation of global CBF. Therefore, this study aim to 1) provide a set of age-specific PC-MRI protocols for CBF quantification in children under 1.5 years old; 2) establish typical arterial flow velocity in children at this age which could guide future ASL efforts in labeling pulse optimization; 3) report how CBF changes during this early stage of life.
