Why USG Pregnancy Anomaly Twins Study is Important
Twin pregnancies carry additional risks compared to single pregnancies. The USG pregnancy anomaly scan ensures that both babies are growing at the correct rate and share resources such as placenta and amniotic fluid appropriately.
This test helps in identifying:
-
Structural abnormalities in the heart, brain, kidneys, or other organs
-
Growth discrepancies between the twins (known as selective growth restriction)
-
Placenta sharing issues like twin-to-twin transfusion syndrome (TTTS)
-
Fetal position, amniotic fluid levels, and overall wellbeing
Choosing the USG pregnancy twins study allows obstetricians to manage any complications early, improving the chances of a safe delivery and healthy newborns.
Benefits of USG Pregnancy Anomaly Twins Study
There are multiple benefits to undergoing a pregnancy anomaly scan for twins:
-
Early and accurate detection of fetal anomalies
-
Assessment of placental and umbilical cord health
-
Monitoring of twin growth rate, symmetry, and wellbeing
-
Helps to plan prenatal care and delivery management
-
Non-invasive, safe, and provides real-time results
The USG twins anomaly scan not only provides peace of mind to expectant parents but also ensures timely medical decisions if any irregularities are found.
How the Test is Done
The USG anomaly scan for twin pregnancy is conducted using high-frequency sound waves. The procedure is painless and typically takes 30-45 minutes.
Here’s what to expect:
-
The patient is asked to lie comfortably on the examination bed.
-
A clear gel is applied over the abdomen to facilitate better image transmission.
-
The sonologist moves a transducer over the belly to capture continuous images.
-
Both babies, their amniotic sacs, and placental structures are observed in real-time.
-
Detailed measurements of head circumference, limb length, and organ growth are recorded.
The scan results are interpreted immediately, and a detailed report is provided to your doctor for further review or follow-up.
Parameters Evaluated During USG Pregnancy Anomaly Twins Study
Key parameters assessed during the ultrasound twin pregnancy study include:
-
Number of fetuses and amniotic sacs
-
Placental position and condition
-
Fetal heart rate and rhythm
-
Fetal biometric measurements (BPD, FL, HC, AC)
-
Brain, spine, heart, stomach, kidneys, and limbs
-
Amniotic fluid volume for each baby
-
Umbilical cord structure and blood flow
These detailed parameters allow healthcare providers to ensure that both babies are developing at a balanced and healthy rate.
When to Get a USG Pregnancy Anomaly Twins Study
The ideal time for the USG pregnancy anomaly test is between 18–22 weeks, as the fetal organs are well-formed and can be clearly visualized. However, in high-risk twin pregnancies, earlier or follow-up scans may be suggested by your gynecologist.
