Summary

To determine the value of principal component analysis in the combined method of three-dimensional ultrasonography assessing fetal limb volume and circumference and conventional two-dimensional ultrasonography for prediction of birth weight in southern Chinese population.

Detailed description

A prospective study was performed on single pregnant women in third trimester. Three- and two-dimensional ultrasonography for fetal biometric parameters were measured within 7 days of delivery. Stepwise linear regression were used to develop a new prediction model based on values from limb parameters and traditional measurements in development group. Estimated and actual birth weight were compared between the new model and previously published formulas on absolute error and percentage error. The accuracy of the model in predicting fetal birth weight was reassured by validation group.

Conditions

• Birth Weight

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	2D and 3D ultrasonography	All of the examinations are performed with the same transabdominal ultrasonic transducer (RAB 2-5-D) on the same E8 (GE Medical Systems, Milwaukee, WI, USA) ultrasonic machine experienced operators. 2D ultrasonic measurements includes 5 standard fetal biometry parameters, and after routine 2D ultrasonography, the acquisition of 3D measurements are performed.
