encephalography

[ensef′əlog′rəfē]
radiographic delineation of the structures of the brain containing fluid after the cerebrospinal fluid is withdrawn and replaced by a gas, such as air, helium, or oxygen. The procedure is used mainly for indicating the site of cerebrospinal fluid obstruction in hydrocephalus or structural abnormalities of the posterior fossa. Because of the risks involved, it is used only when results of computed tomography are not definitive. Kinds of encephalography are pneumoencephalography and ventriculography. Also called air encephalography. Compare echoencephalography, electroencephalography. encephalographic, adj.

encephalography

Any X ray examination of the brain. In air encephalography, the cerebrospinal fluid in the brain ventricles is replaced by air. CT SCANNING and MRI have rendered this very unpleasant procedure obsolete.

encephalography

radiography demonstrating the intracranial fluid-containing spaces after the withdrawal of cerebrospinal fluid and introduction of air or water-soluble contrast media. Called also pneumoencephalography, ventriculography, cerebral ventriculography.
