Diagnostic ultrasound examination is employed in a variety of specific circumstances during pregnancy, such as where there are concerns about fetal growth and after clinical complications. However, because adverse outcomes may also occur in pregnancies without clear risk factors, assumptions have been made that antenatal ultrasound examination in all pregnancies will prove beneficial by enabling earlier detection of problems that may not be apparent 3 — such as multiple pregnancies, IUGR, congenital anomalies, malpresentation and placenta praevia — and by allowing accurate gestational age estimation, leading to timely and appropriate management of pregnancy complications. The ANC recommendations are intended to inform the development of relevant health-care policies and clinical protocols.
