Abstract
Cardiac related motion of the cerebrospinal fluid (CSF) was investigated by analysis of the velocity dependent phase of CSF protons and flow dependent signal enhancement in magnitude images using ECG-gated MRI gradient-echo techniques. In the cerebral aqueduct systolic CSF-flow from the third to the fourth ventricle starts 200 msec after the R-wave of the ECG and is followed by a diastolic backflow which shows a slower velocity and takes a shorter time. In the spinal canal, the systolic motion downwards precedes the aqueductal CSF flow downwards for about 100 msec.
