[Measurements of the intracranial CSF spaces by computer tomography (author's transl)].

A method for quantifying the CSF compartments in cranial computer tomograms is described. The method is based on an analysis of the histogram curve, the proportion of area and thickness of the liquor spaces being related to the total area below the curve. In order to isolate the skull contents, a CT masking technique is used. The practicability and usefulness of the method in clinical practice was tested in 59 normal patients and in eleven patients with rapidly progressing brain atrophy.
