Use of 3D/4D Ultrasound in the Evaluation of Fetal Anomalies
Use of 3D/4D Ultrasound in the Evaluation of Fetal Anomalies

The usage of 3D/4D in additional to 2DUS can improve the assessment of structural anomalies at early gestation (11 to 14 weeks gestation), improve in the prediction of birth weight, decrease maternal anxiety and increase maternal-fetal bonding compared to 2DUS, 3DUS can be used to measure fetal volume, gestational sac and placenta volume with different methods (multiplanar, VOCAL and XIVOCAL, to measure fetal, gestational sac and placenta volume for alpha(0)thalassaemia studies and comparison between 2 ultrasound machines (Accuvix and Voluson 730).

This study is carried out to do:

  1. to determine if the use of 3D/4D ultrasound at 11-14 weeks gestation can increase the accuracy in the detection of fetal abnormalities, reduce maternal anxiety (in both short and long term), improve maternal-fetal bonding (in both short and long term) and improve the accuracy of the prediction of birth-weight over 2D ultrasound alone
  2. to determine if there is any difference in the measurement of fetal volume between two models of 3D ultrasound machines (Voluson 730 and Accuvix)
  3. to determine if there is any difference in the measurement of fetal volume among three methods (multiplanar, VOCAL, XIVOCAL)
  4. to determine if there is any difference in the measurement of placenta volume among three methods (multiplanar, VOCAL and XIVOCAL)
  5. Measurement of fetal, gestational sac and placenta volume for alpha(0)thalassaemia patients at 11-14 weeks of gestation

Inclusion Criteria:

  • Women are recruited from our prenatal diagnostic clinic at Ysan Yuk Hospital before 14 weeks gestation. They are those who come for routine scan and those who are referred from the general antenatal clinics of the same hospital. Their pregnancies are at risk of fetal abnormalities because of advanced maternal age, a family or previous history of congenital abnormalities, an abnormal Down syndrome screening test, drug intake in early pregnancy or maternal disease

Exclusion Criteria:

  • If women refuse to participate in the study
