Eighty-two normal fetuses were scanned from 18 to 41 weeks of gestation. The following M-mode measurements were correlated with the abdominal circumference: diastolic biventricular outer (r = 0.951) and inner (r = 0.948) dimensions; diastolic right (r = 0.942) and left (r = 0.925) internal dimensions; tricuspid (r = 0.916) and mitral (r = 0.900) valve opening excursions; and right (r = 0.774), left (r = 0.731), and interventricular septal (r = 0.753) wall thickness. Polynomial regression demonstrated that linear regression best described the data from which the mean and 5 per cent and 95 per cent confidence limits for predicted M-mode measurements were computed for the abdominal circumference between 12 and 35 cm.
对82例孕18至41周的正常胎儿进行了扫描。以下M型测量值与腹围相关：舒张期双心室外径（r = 0.951）和内径（r = 0.948）；舒张期右室内径（r = 0.942）和左室内径（r = 0.925）；三尖瓣（r = 0.916）和二尖瓣（r = 0.900）瓣口开放幅度；以及右室壁（r = 0.774）、左室壁（r = 0.731）和室间隔壁厚度（r = 0.753）。多项式回归表明，线性回归最能描述这些数据，据此计算出腹围在12至35 cm之间时预测M型测量值的均值以及5%和95%的置信区间。
