Scheme of the human brain CSF system. The velocity of the CSF per unit time within the aqueduct is measured by the phase-contrast magnetic resonance imaging (PC–MRI) method. Inset is the aqueduct of Sylvius, which is considering to be a cylinder through which the CSF passes. The CSF production rate is calculated using an equation based on CSF velocity using the MRI method
