U.S. Naval Hospital, Charleston, SC: Viewing Head X-Rays

    the x-ray images are pneumoencephalograms. pneumoencephalography (peg) was a method that allowed for more detailed brain x-rays. the csf was drained from the spinal canal and replaced with air that was forced to travel to the brain (the ventricles) via a special swiveling chair in which the patient had to be strapped in.
    then the head was x-rayed in various position.
    this procedure caused serious headaches and severe vomiting which could last for several days. with the advent of modern imaging techniques such as ct it became obsolete.
    good riddance!
