We applied 2D cine-PC MRI to investigate the intracranial compliance of 29 healthy term neonates and children. Cerebral blood volume expansion, during cardiac cycle, was calculated from internal carotid and vertebral arteries and jugular veins' flows. The cerebrospinal fluid volume flushing out of the cranium owing to intracranial pressure increase was measured at the cervical level. An index of intracranial compliance, defined as the ratio of blood and CSF volume changes during the cardiac cycle, was calculated. We have demonstrated that intracranial compliance variations during the first months of life could be studied using PCMRI
