Abstract
|
|
|
|
The use of MRI to study CSF flow in the brain was mainly by flow void signal on T2WI or hydrodynamic study with phase-contrast cine MRI. Authors pay attention to high signal intensity in CSF passway on fast FLAIR MR image of the brain, usually known as the artifact. The conclusions are as below ; 1. The high signal intensity appeared in CSF passway on fast FLAIR MR image of the brain near constantly. 2. The high signal intensity was best visualized on image perpendicular to the CSF flow. 3. The high signal intensity was related to the velocity of the fluid not to the direction of the fluid.
