title: [The advantages and limitations of an automatic ultrasound determination of the cerebral midline--a study of 1889 cases].
abstract: The examination of the brain with ultrasound has become an indispensible diagnostic tool in all cases of intracranial pathology. Valuable information is obtained both in emergencies and in follow-up studies. Since long practice is necessary before the results of echoencephalograms can be interpreted accurately, a need was felt for a standardization of the examination which would eliminate the subjective influence of the investigator. The automatic midline computer, called Midliner, which has recently become available, makes fewer demands on the experience of the investigator although the diagnostic possibilities are not as broad. The position of the midline echo is of primary interest, although the width of the third ventricle can be successfully determined in occasional cases. this study, which presents the results of the Midliner examinations in three clinics, is grouped according to diagnosis. Through a comparison with conventional A-scan echoencephalograms, as well as with neuroradiological and operative findings in 1889 cases, the reliability of this method is clearly demonstrated. The advantages and disadvantages of the examination are discussed and the field of application indicated.
