Understanding obstetric ultrasound: A key to monitoring pregnancy health
Written in association with:Obstetric ultrasound is a crucial tool in prenatal care, offering expectant parents and healthcare providers detailed insights into the health and development of a baby during pregnancy. This non-invasive imaging technique uses high-frequency sound waves to produce real-time images of the fetus, uterus, and other surrounding structures.
These images help monitor the baby's growth, check for potential abnormalities, and assess the overall progress of the pregnancy. Here to explain more is esteemed consultant obstetrician and gynaecologist, Dr Koon Loong Chan.
When does the first ultrasound take place in a pregnancy cycle?
The first ultrasound typically occurs in the early stages of pregnancy, usually between 6 to 10 weeks. This early scan confirms the pregnancy, estimates the due date, and checks for the presence of multiple fetuses. It also verifies the baby’s heartbeat, providing reassurance to the parents.
One of the most important scans is the "anomaly scan," performed between 18 to 22 weeks. This detailed ultrasound assesses the baby’s anatomy, including the heart, brain, spine, and limbs, ensuring that all major organs are developing properly. It also checks for any structural abnormalities, such as cleft palate or heart defects. During this scan, parents can also choose to find out the baby’s gender, if desired.
Later in pregnancy, ultrasounds may be used to monitor the baby's growth, check the position of the baby, and evaluate the health of the placenta and amniotic fluid levels. These scans are particularly important in high-risk pregnancies, where frequent monitoring is needed to ensure the well-being of both mother and baby.
Obstetric ultrasound is safe and painless, providing real-time information that guides medical decisions and helps ensure a healthy pregnancy and delivery. Whether confirming the early stages of pregnancy or monitoring the baby’s development, ultrasounds offer a window into the womb and provide peace of mind for expectant parents.
