Abstract

Cerebral fluid (CSF) in the cranial cavity flows toward the spinal CSF space in a to and fro manner, responding to the pulsations of the brain. Therefore, the signal intensity of the CSF on magnetic resonance imaging (MRI) is affected and changed by the velocity of CSF flow (Bradley et al. 1986, Sherman and Citrin 1986). In general, the signal intensity of flowing fluid becomes less when the flow velocity is greater. Fluid flowing rapidly beyond some threshold value loses its signal on MRI. This is termed the signal void phenomenon (SVP).
