Fig. 5From: Hyperdynamic CSF motion profiles found in idiopathic normal pressure hydrocephalus and Alzheimer’s disease assessed by fluid mechanics derived from magnetic resonance imagesRotation mapping of the volunteer by 3D-PC at 4 stages of the cardiac cycle. In-plane rotations were visualized using vectors and through-plane rotations were visualized using colors. The color-coded CSF rotation field vector was then superimposed onto T2-weighted images of the stationary tissues. Red circle indicates Sylvian aqueductBack to article page
