Evaluation of more than 1500 cases has shown that real foetal weight can be calculated on the basis of mean thorax diameter, if linear ultrasonic measures are used. Addition of more parameters will render calculation more sophisticated and complex, though gain in accuracy will be unimportant. Accuracy depends not only on biological variation but even more on precise measurement by the examiner. An aid for more convenient calculation is described.
对1500多例病例的评估表明，如果采用线性超声测量方法，可根据平均胸廓直径计算出实际胎儿体重。增加更多参数会使计算变得更精细复杂，不过准确性的提高并不显著。准确性不仅取决于生物学变异，更取决于检查者的精确测量。本文介绍了一种便于计算的辅助方法。
