本文对100例胎龄14 ~ 38周的正常胎儿的心室心房进行了测量，并与38例宫内诊断为心室肥大的胎儿进行了比较。通过侧脑室心房的脑轴向超声图表明，正常心房直径在整个胎龄范围内保持相对恒定。心房的平均直径为7.6 ± 0.6 mm（标准差[SD]）。这种结构的测量可以快速进行，是可重复的，观察者内和观察者间的变化很低，并允许心室扩大被排除在外。心房直径超过10 mm（大于4个标准差）提示心室扩大，假阳性率低。
The ventricular atria in 100 healthy fetuses with gestational ages ranging from 14 to 38 menstrual weeks were evaluated and compared with those of 38 fetuses in whom ventriculomegaly had been diagnosed in utero. Axial sonograms of the brain through the atrium of the lateral ventricle demonstrated that the normal atrial diameter remained relatively constant throughout the gestational age range observed. The atrium had a mean diameter of 7.6 +/- 0.6 mm (standard deviation [SD]). Measurement of this structure can be quickly performed, is reproducible with low intra- and interobserver variation, and permits ventriculomegaly to be excluded. Atrial diameters exceeding 10 mm (above 4 SDs) suggest ventriculomegaly, with a low false-positive rate.
