Improved gray scale ultrasonic equipment has made two-dimensional echoencephalography a useful diagnostic tool in the examination of the infant brain for fluid-containing structures such as dilated ventricles and cysts. Eighteen infants have been examined to exclude hydrocephalus and other abnormalities. Ten had significantly dilated lateral ventricles and three of these were shown to have associated intracerebral abnormalities. Another infant was demonstrated to have an arachnoid cyst or subdural hygroma with normal size ventricles. Ten of the 11 abnormalities were confirmed by some other neuroradiologic study.
改进后的灰阶超声设备使二维脑回波描记术成为检查婴儿脑部含液结构（如脑室扩张和囊肿）的一种有用诊断工具。已对18名婴儿进行检查以排除脑积水和其他异常情况。10名婴儿有明显扩张的侧脑室，其中3名显示伴有脑内异常。另一名婴儿被证明有蛛网膜囊肿或硬膜下积液，脑室大小正常。11例异常中有10例经其他神经放射学检查得到证实。
