Technique for X-ray visualization of some brain tissues that involves the injection of oxygen or other gas into the ventricles of the brain to displace cerebrospinal fluid and provide a contrast medium.
An X-ray study of fluid-containing structures of the brain, using sterile gas injected into the spinal cord as contrast medium.
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.
An obsolete term for radiography of the ventricles and subarachnoid spaces of the brain following withdrawal of cerebrospinal fluid and injection of air or gas via lumbar puncture. This technique has been replaced by computed tomography and magnetic resonance imaging.
