Early Anomaly Scan: Detecting Structural Abnormalities in Early Pregnancy
The Early Anomaly Scan is a vital prenatal ultrasound performed during the first or early second trimester to evaluate the baby’s development and detect structural abnormalities. This scan helps in early planning, monitoring, and intervention for a healthy pregnancy journey.
What Is an Early Anomaly Scan?
An Early Anomaly Scan examines the baby’s anatomy and growth to identify structural changes or abnormalities that may require further assessment.
It can detect issues such as:
- Neural tube defects (e.g., spina bifida)
- Abdominal wall defects
- Heart anomalies
- Skeletal malformations
- Other early congenital conditions
Why Is an Early Anomaly Scan Important?
1. Early Detection of Problems
Identifying structural abnormalities early allows for timely management, counselling, and planning.
2. Pregnancy Planning
Early insights help doctors prepare for interventions if needed and guide parents on the pregnancy journey.
3. Peace of Mind
Even if everything is normal, an early scan reassures parents about fetal growth and wellbeing.
When Is an Early Anomaly Scan Done?
| Gestational Age | Purpose |
|---|---|
| 13–16 weeks | Ideal window for early structural assessment |
| Before 13 weeks | Structures may not be clearly visible |
| After 16 weeks | May require a detailed Level II anomaly scan instead |
How Is the Early Anomaly Scan Performed?
-
Abdominal ultrasound is the most common method
-
Transvaginal scan may be used for better clarity in some cases
-
The sonographer examines:
- Head and brain structures
- Face and neck
- Heart chambers and major blood vessels
- Spine and limbs
- Abdomen, kidneys, and bladder
- Placenta and amniotic fluid levels
Is the Early Anomaly Scan Safe?
Yes. It is non-invasive, painless, and safe for both the mother and baby, using high-frequency sound waves.
Who Should Get an Early Anomaly Scan?
- All pregnant women as part of routine antenatal care
- Women with previous pregnancy complications
- Advanced maternal age (≥35 years)
- Pregnancies conceived via IVF
- Family history of congenital abnormalities
FAQs – Early Anomaly Scan
What does an Early Anomaly Scan detect?
It screens for structural defects in the baby’s organs, limbs, and body, providing early insight into potential congenital conditions.
Is it compulsory?
It is not mandatory but strongly recommended for early detection of structural abnormalities.
Is the scan safe for the baby?
Yes. It uses ultrasound, which is non-invasive and safe during pregnancy.
Can Early Anomaly Scan detect genetic conditions?
No. It identifies physical structural abnormalities but not genetic or chromosomal disorders. For genetic screening, other tests like NT scan or NIPT are required.
Do I need to prepare for this scan?
Usually, a moderately full bladder is recommended for better imaging. Your doctor will guide you on preparation.
Will this scan determine gender?
Gender identification may sometimes be visible but is not the primary purpose of the scan.
What if abnormalities are detected?
Further tests, detailed Level II anomaly scan, or specialist consultation will be recommended to assess the situation thoroughly.
Conclusion
The Early Anomaly Scan is a crucial step in prenatal care, helping detect structural issues early and enabling proactive pregnancy management. Early insights empower parents and doctors to plan for a safer and healthier pregnancy journey.
