Anatomical and Technical Causes of Errors in Echo-Encephalography
The technique of echo-encephalography was described in detail in the German literature years ago, particularly by Schiefer, Kazner, BrüCkner (1963) and Kramer (1963). The authors emphasized that abnormal findings must be reproducible over several measurements before they can be regarded as pathological. Feuerlein and Dilling (1965) clearly demonstrated the possibilities of checking the accuracy of the echo-encephalographic measurements of the third ventricle. Nevertheless, we believe it is necessary to point out once again several causes of fallacious measurements or misinterpretations and how to avoid them.
