To
study the spatial and temporal dynamics of CSF flow in the ventricular system
of 40 normal volunteers using time-resolved 3D magnetic resonance velocity
mapping. Classification of CSF flow based on calculation of 3D particle path
lines over the cardiac cycle revealed one uniform flow pattern for the
lateral ventricles, three categories for the third and two categories for the
fourth ventricle. We found no significant aging effects on both the presence
of a specific CSF flow pattern and on flow velocities. Our results provide
the first detailed demonstration of the anatomy of CSF flow within the human
ventricular system.
