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 and build up nomogram for palate studies at 11 - 14 weeks gestation, to measure fetal, gestational sac and placenta volume for alpha(0)thalassaemia studies and four-dimensional fetal echocardiography with spatiotemporal image correlation (STIC)can be used as a systematic study of standard cardiac views assessed by different observers
