Abstract

It is believed that both the Recording and Interpretation of Echoencephalograms can be influenced by the operator and interpreter. Such influence is used to choose the most suitableM-echo where more than one possibility exists. When a skilled clinician performs the test, he uses clinical information gained from the patient and other sources to influence the results towards increased accuracy. It is for this reason that the most accurate results are obtained when echoencephalography is carried out and interpreted by a skilled clinician.

If echoencephalography must be performed largely by skilled physicians, the limited clinical information it gives would not seem to justify the expenditure of time by such an operator. We believe attempts should be made to develop a more objective technique that can be used accurately by technical personnel.

Sommaire

On pense que l'Enregistrement et l'interpretation des Echo-encéphalogrammes peuvent être influencés par l'opérateur et par l'interprête. Une telle influence est utilisée pour choisir l'écho M le plus convenable où plus d'une possibilité existe. Lorsqu'un clinicien expert entreprend l'essai, il utilise les renseignements clinicaux obtenus du patient et d'autres sources pour influencer les résultats vers une précision améliorée. C'est pour cette raison que les résultats les plus précis sont obtenus lorsque l'échoencéphalographie est menée et interprètée par un expert clinicien.

Si l'échoencéphalographie doit être entreprise surtout par des docteurs spécialistes, les renseignements clinicaux limités obtenus ne justifieraient pas la dépense en temps d'un tel opérateur. Nous pensons qu'il serait bon d'essayer de développer une technique plus objective qui serait utilisable de façon précise par le personnel technique.

Zusammenfassung

Man ist der Meinung, dass sowohl Aufnahme wie Deutung von Echo-Enzephalogrammen von dem Ausführenden und dem Deuter beeinflusst werden können. Dieser Einfluss wird angewandt, um das geeignetste, M-Echo zu wählen wenn mehr als eine Möglichkeit besteht. Wenn ein erfahrener Kliniker die Untersuchung durchführt benutzt er klinische Informationen, die er vom Patienten gewonnen hat und andere Quellen, um die Ergebnisse für eine grössere Genauigkeit zu beeinflussen. Aus diesem Grunde, werden daher die genauesten Ergebnisse erhalten, wenn die Echo-Enzephalographie von einem erfahrenen Kliniker durchgeführt und gedeutet wird.

Wenn Echo-Enzephalographie hauptsächlich von erfahrenen Internisten ausgeführt werden soll, erscheint die begrenzte klinische Information, die sie gibt, nicht den Zeitverbrauch einer solchen Betätigungsperson zu rechtfertigen. Wir sind der Meinung, dass Versuche für Entwicklung einer objektiveren Technik gemacht werden sollten, welche mit Genauigkeit mit technischem Personal verwandt werden kann.
