Echoencephalographic A-scan study of the aqueduct and brain stem.
The author utilizes autopsy models and normal clinical subjects with and without pneumoencephalography to demonstrate the value of echoencephalography in delineating the position of the aqueduct of Sylvius. Echoes from the dorsum sellae, the anterior wall of the sella turcica, and the aqueduct proved consistently identifiable, while echoencephalographic examination of 25 normal subjects revealed in all instances well-defined aqueduct echoes. Thus the aqueduct echo method may be a diagnostic aid in determination of the anterior-posterior position of the brain stem.
