Pneumoencephalography (sometimes abbreviated PEG; also referred to as an " air study ") was a common medical procedure in which most of the cerebrospinal fluid (CSF) was drained from around the brain by means of a lumbar puncture and replaced with air, oxygen, or helium to allow the structure of the brain to show up more clearly on an X-ray image.
May 18, 2022 · Pneumoencephalography was said to be an extremely unpleasant undertaking for patients who commonly experienced severe headaches, nausea, diaphoresis, lassitude, and hypotension 4.

Pneumoencephalography. Pneumoencephalography (abbreviated as PEG; sometimes called an ‘air study’) is an old invasive technique that involved the draining of the majority of the cerebrospinal fluid (CSF) from around the brain through a lumbar puncture. The CSF was replaced with air, oxygen, or helium to enable the structure of the brain to ...
Definition. A pneumoencephalogram was once a common medical imaging procedure, introduced in 1919 by an American neurosurgeon Walter Dandy. The procedure involved a lumbar puncture, with the removal of a small volume of cerebrospinal fluid and injection of air, oxygen, or helium in its place. The gas would naturally displace fluid and rise to ...
