Ultrasonographic fetal biometrical measurements as a predicator of gestational age

ABSTRACT

Ultrasonographic examinations were performed to 189 pregnant Egyptian wome in Al-Zahraa and Said Galal University Hospital. Sonograhic identification and measurements of head and abdominal circumference. Liver. Kidney, femur and foot length were preformed between 20 and 40 weeks gestation. A highly significant correlation was found between the previous fetal biometrical parameters and gestational age and also between each other. An equation from each parameter was concluded by using simple linear regression to calculate the expected gestational age per week. A general equation was deduced from all previous fetal parameters to predict the gestational age
