Views are obtained using an abdominal ultrasound probe, but a vaginal ultrasound probe may also be used to evaluate for placenta previa and cervical length. Three-dimensional (3D) ultrasound is not recommended for routine use during anomaly scan, but 3D ultrasound may be used to further evaluate suspected abnormalities in specific fetal ...
