Fetal Anomaly Scan

Fetal Anomaly Scan

A fetal anomaly scan, also known as a mid-pregnancy ultrasound or anomaly scan, is a detailed ultrasound examination performed between 18 to 21 weeks of pregnancy. The primary purpose of this scan is to assess the development of the fetus and detect any structural abnormalities or congenital anomalies. It is a crucial part of prenatal care and provides valuable information about the health and well-being of the developing baby.

During a fetal anomaly scan, a trained sonographer or obstetrician uses a transducer to emit high-frequency sound waves through the mother's abdomen. These sound waves create real-time images of the fetus, which are displayed on a monitor. The sonographer carefully examines the fetus's anatomy, including the brain, heart, spine, limbs, kidneys, and other vital organs, to ensure they are developing normally.

The anomaly scan can identify a wide range of structural abnormalities, such as neural tube defects (e.g., spina bifida), heart defects, abdominal wall defects, and limb abnormalities. It can also detect conditions like cleft lip and palate, certain skeletal dysplasias, and some chromosomal anomalies that may present with physical markers, such as Down syndrome. Additionally, the scan assesses the position of the placenta, the amount of amniotic fluid, and fetal growth parameters.

If any anomalies or concerns are identified during the scan, further investigations or follow-up scans may be recommended to confirm the findings and assess their significance. In some cases, additional tests such as amniocentesis or chorionic villus sampling (CVS) may be suggested to provide more detailed information about the fetus's genetic health. The results of the anomaly scan can help healthcare providers plan appropriate care and interventions, both during the pregnancy and after birth, to ensure the best possible outcomes for the baby and mother.

The fetal anomaly scan is a safe and non-invasive procedure that poses no risk to the mother or baby. It provides an opportunity for expectant parents to see their developing baby and gain reassurance about the baby's health and development. While the primary goal is to detect any potential issues, many parents also look forward to this scan as it often includes the first detailed images of their baby.
