title: [Computerized tomography studies of age- and sex-related physiological variations of intracranial structures].
abstract: This paper supplies proof of the age dependence of the physiological cerebral density and ventricle size. The studies are based on the evaluation of normal cerebral computer tomograms of a total of 1100 patients of both sexes. Mathematical statistical calculations yield accurate data on the age-conditioned physiological "standard ranges" of cerebral density and ventricle width (3rd and 4th ventricle). By means of the graphic representations and calculation formulas it is possible to achieve rapid orientation provided the CT technique employed is the same. The results as communicated in this paper enable further quantification and objectivation of our CT data.
