The author describes a method of identifying and measuring the fetal biparietal diameter ultrasonically, based on an anatomical pattern. This pattern takes the form of an arrow whose components lie in both the sagittal and coronal planes. It is a practical method of obtaining adequate and consistent biparietal measurements in both A/B-scan and real-time modes; in 100 patients studied both ways, the mean difference was 0.0632 mm.
作者描述了一种基于解剖学模式超声识别和测量胎儿双顶径的方法。这种模式呈箭头状，其组成部分位于矢状面和冠状面。这是一种在A/B超和实时模式下获得足够且一致双顶径测量值的实用方法；对100例患者采用这两种方式进行研究，平均差值为0.0632毫米。
