n.
a technique used in the X-ray diagnosis of disease within the skull. Air is introduced into the cavities (ventricles) of the brain to displace the cerebrospinal fluid, thus acting as a contrast medium. X-ray photographs show the size and disposition of the ventricles and the subarachnoid spaces. The technique has largely been superseded by CT and MRI scanning.

pneu·mo·en·ceph·a·log·ra·phy (PEG) (noo″mo-ən-sef″ə-logґrə-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radiographic visualization of the fluid-containing structures of the brain after cerebrospinal fluid is intermittently withdrawn by lumbar puncture and replaced by air, oxygen, or helium; this procedure is no longer performed, having been replaced by metrizamide cisternography.
