About this test
What is a Pregnancy Ultrasound – Detailed Baby Anomaly Scan?
A detailed anomaly scan is an ultrasound performed usually between 18‑22 weeks of pregnancy. It uses sound waves to create a live image of the baby inside the uterus, allowing the doctor to check the baby’s growth, position and the development of major organs.
Key parameters reported
| Parameter | What it shows |
|---|---|
| Fetal size (BPD, HC, AC, FL) | Growth and weight estimation |
| Fetal anatomy (brain, heart, spine, limbs, kidneys, abdomen, face) | Detection of structural abnormalities |
| Placenta location and thickness | Placental health and position |
| Amniotic fluid volume | Adequate fluid for fetal movement |
| Fetal heart rate | Cardiac function |
Why is it done?
- Routine check‑up in the second trimester.
- Evaluate symptoms such as abdominal pain or bleeding.
- Monitor pregnancies at higher risk (e.g., previous baby with a defect, maternal age >35, family history of congenital anomalies).
- Provide reassurance about fetal development.
Early detection
This scan can help identify signs of congenital heart disease, neural tube defects, cleft lip/palate, kidney malformations, and other structural problems, but it does not diagnose on its own. A doctor interprets the results together with symptoms, history, and other tests.
What an abnormal result may mean
An abnormal finding could indicate a structural defect, growth restriction, or other issue. Many factors such as maternal hydration, medication, or technical aspects can influence measurements, so repeat scans or additional tests may be needed.
Who might be advised to get this test?
- All pregnant women, especially between 18‑22 weeks.
- Women with risk factors: advanced maternal age, previous pregnancy with a defect, certain medical conditions (e.g., diabetes), or a family history of congenital anomalies.
Quick summary
A detailed anomaly scan is a safe, non‑invasive ultrasound that checks the baby’s growth and major organs, helping to spot potential problems early.
Used for detecting / monitoring
Before your test
Preparation for the Scan
- Fasting: No fasting required.
- If combined with a fasting test (e.g., blood glucose), follow the strictest instruction – usually 8‑12 hours of fasting.
- Procedure: A gel is applied to the abdomen, and a transducer moves over the skin to capture images. The scan takes about 20‑30 minutes.
- What to expect: The procedure is painless. You may feel a slight pressure from the transducer.
- Precautions: No special medication timing or hydration instructions are needed, but avoid alcohol and strenuous exercise 24 hours before if you are also doing other tests.
- Note: Confirm specific preparation with your doctor or the lab. This information is general educational material and not a substitute for professional medical advice.
Sample type: Imaging
Report parameter guide
Fetal Heart Rate
The number of heartbeats per minute of the fetus
Low: May indicate fetal distress or hypoxia
High: May indicate fetal distress or hyperthyroidism
Nuchal Translucency Thickness
The fluid-filled space at the back of the fetal neck measured in the first trimester
Low: Usually within normal limits
High: May indicate chromosomal abnormalities or structural heart defects
Estimated Fetal Weight
An estimate of the baby’s weight based on ultrasound measurements
Low: May indicate growth restriction or placental insufficiency
High: May indicate macrosomia or gestational diabetes
Biparietal Diameter
The width of the fetal skull between the parietal bones
Low: May indicate growth restriction
High: May indicate macrosomia
Femur Length
The length of the fetal thigh bone
Low: May indicate growth restriction
High: May indicate macrosomia
Abdominal Circumference
The circumference of the fetal abdomen
Low: May indicate growth restriction or fetal anemia
High: May indicate macrosomia or gestational diabetes
Amniotic Fluid Index
A measurement of the fluid volume surrounding the fetus
Low: May indicate oligohydramnios, fetal renal problems or placental insufficiency
High: May indicate polyhydramnios, fetal urinary tract obstruction or gestational diabetes
Placenta Location
The position of the placenta in the uterus
Fetal Position
The orientation of the fetus in the uterus (e.g., cephalic, breech)
Fetal Anomaly Assessment
Overall evaluation of fetal anatomy for structural abnormalities
