预测胎儿体重的非线性模型
Nonlinear Model of the Prediction of Fetal Weight
【摘要】 应用 B型超声对 5 1 6例胎儿的股骨长、双顶径、腹围进行测量 ,经非线性回归分析得出预测胎儿体重的模型 ,并且应用这些模型对 1 2 0例胎儿进行前瞻性验证
【Abstract】 By ultrasonic measurements of betal biparietal diameter (BPD) femur length(FL) and abdominal circumference (AC) in 516 cases. The models of the prediction of fetal weight are established by using of nonlinear regression. Prospective study of the effects of the biparietal diameter, femur length and abdominal circumference in estimation of fetal weight in 120 case.
