Fig. 1

Velocity mapping of the volunteer by 3D-PC at 4 different stages of the cardiac cycle. In-plane velocities were visualized using vectors and through-plane velocities were visualized using colors. The color-coded CSF velocity field vector was then superimposed onto T2-weighted images of the stationary tissues. Red circle indicates Sylvian aqueduct
