Methods of measurement in encephalography

Abstract

In a series of 114 cases of pneumoencephalography it has been demonstrated that there is relatively good agreement among 4 different methods of encephalo-graphic measurements: Schiersmann''s, Evans'', determination of the length of both cellae mediae, and determination of the length of the septum caudate line. The last 2 mentioned are almost of equal value. It has been shown that a single measurement from various methods may result in a surprisingly good correlation, but supplementary measurements seem to increase the value of all methods and their correlation.
