Pneumoencephalography

pneumoencephalography

[¦nü·mō·in‚sef·ə′läg·rə·fē] (medicine) A method of visualizing the ventricular system and subarachnoid pathways of the brain by roentgenography after removal of spinal fluid followed by the injection of air or gas into the subarachnoid space.

Pneumoencephalography

(also cerebral pneumography, encephalography), X-ray examination of the brain by artificially contrasting the fluid-containing spaces. The procedure was introduced in 1918 by the American neurosurgeon W. Dandy. The contrasting agent is usually air or oxygen; it is most commonly injected by means of cerebrospinal puncture. After injection of the contrasting agent, an X ray of the skull is taken in various projections.

Pneumoencephalography is used as a diagnostic tool to detect various changes in the ventricles, cisternae, and fissures of the subarachnoid cavity of the brain (enlargement, constriction, shifting).

In modern neurology the term “encephalography” is used to designate any one of various methods of examining the brain.

pneumoencephalography

(PEG) [noo″mo-en-sef″ah-log´rah-fe] radiographic visualization of the fluid-containing structures of the brain after cerebrospinal fluid is intermittently withdrawn by lumbar puncture and replaced by air, oxygen, or helium.

pneu·mo·en·ceph·a·log·ra·phy

(nū'mō-en-sef'ă-log'ră-fē), Radiographic visualization of cerebral ventricles and subarachnoid spaces by use of gas such as air; no longer used because of CT and MRI. [G. pneuma, air, + enkephalos, brain, + graphō, to write]

pneumoencephalography

A method of X-ray examination of the VENTRICLES of the brain in which the CEREBROSPINAL FLUID is replaced by air. This very unpleasant procedure has been rendered obsolete by CT SCANNING and MRI.
