Abstract
Although echoencephalography is a simple, convenient and atraumatic diagnostic technique, the accuracy and reliability of this test and whether it is reproducible can be greatly influenced by the way in which the examination is performed and subsequently analyzed. Echoencephalography in 850 patients has led to the development of a standardized technique which takes into account the positioning of the patient, the application of the transducer, the identification of the midline-echo-complex, and the elimination of observer bias. Once performed the test must meet rigid standards of acceptability. If acceptable the test is analyzed according to an established format.
