DIAGNOSTIC PROCEDURES :
A spinal fluid exam or spinal tap involves the withdrawal by special needle under sterile conditions, and subsequent
laboratory examination, of a small amount
of cerebrospinal fluid for the diagnosis of polio, meningitis, brain tumors, and other conditions. The echoencephalogram gives
a picture of, and shows irregularities
in, a persons brain waves.
uses ultrasonic waves, rather than the electric currents of the EEG, to investigate the functioning of the brain. A brain Scan
calls for the injection of a radioactive element into the brain tissue or fluid and records its movements on a photographic plate.
Recently, an X-ray technique utilizing a computer and known as CAT scanning (for computerized, axial tomography) has proved to be most effective for visualizing “slices “of the brain that would otherwise be inaccessible, and no injection is necessary. Sometimes called a brain scanner, the device takes a series of pictures as it is rotated around the patient. From data fed into a computer, the computer generates composite pictures of the brain.
The cerebral arteriogram is a method of visualizing and assaying brain damage by injecting a dye into the blood vessels serving the brain and then X-raying them. It is especially useful in judging the severity
and location of hemorrhages and strokes. A pneumoenecephalogram is an X-ray picture of. The Brain taken after air or gas been injected into the ventricles of the brain..
