Predictive value and accuracy of prenatal four-dimensional color ultrasound for fetal abnormal development.

To investigate the value and accuracy of prenatal GE-E10 ultrasound Equipment in predicting fetal abnormal development. 160 pregnant women and women who received prenatal ultrasound examination were selected. Before delivery, all pregnant women were examined by conventional two-dimensional and four-dimensional (4D) ultrasound. 18 fetuses with abnormal development were detected by gold standard in 160 pregnant women. Sensitivity and specificity of two-dimensional color ultrasound in diagnosing fetal abnormal development were 78.38% and 82.60%. The sensitivity and specificity of 4D color ultrasound in diagnosing fetal abnormal development were 81.15% and 83.43%. ROC showed that the AUC (0.873) of 4D color ultrasound was higher than that of two-dimensional color ultrasound (0.827). The diagnostic efficiency of 4D ultrasound is greater. The accuracy, specificity and sensitivity of 4D color ultrasound in the diagnosis of fetal abnormal development is high, and it is valuable for prenatal screening of macrosomia and low birth weight.
