Our expert team performs highly resolved ultrasound examinations to precisely determine the growth and development of twin pregnancies earlier while screening for chromosomal abnormalities.
About USG OBS NT-NB with Twins
USG OBS NT-NB with Twins is a specialized first-trimester ultrasound that is performed between 11-13 weeks and 6 days of pregnancy. The scan assesses both fetuses in a twin pregnancy by assessing the presence of the nasal bone (NB) and by measuring the Nuchal Translucency (NT).
At Molecular Diagnostics and Therapy, our team uses advanced laboratory technologies that include advanced ultrasound, which provides detailed fetal assessment and helps obstetricians to identify pregnancies that require closer monitoring.
What is a USG OBS NT-NB with Twins Scan?
The examination also determines whether the twins share the same placenta (chorionicity) or have separate placentas, as well as whether they share the same amniotic sac (amnionicity). This information is essential for planning antenatal care and monitoring potential twin pregnancy complications.
A USG OBS NT-NB with Twins is an ultrasound that is specifically designed for twin pregnancies. Each fetus is assessed for growth separately, heart activity, nuchal translucency thickness, and nasal bone visualization during the scan.
Common Reasons for USG OBS NT-NB with Twins
- First-trimester screening in twin pregnancy
- Assessment of fetal viability
- Measurement of nuchal translucency (NT)
- Evaluation of nasal bone (NB)
- Confirmation of gestational age
- Determination of chorionicity and amnionicity
- Early screening for chromosomal abnormalities
- Assessment of early fetal anatomy
- Monitoring twin pregnancy development
- Evaluation before combined first-trimester screening tests
Conditions Evaluated
Chromosomal Abnormality Screening
Measures nuchal translucency and evaluates the nasal bone to estimate the risk of conditions such as Down syndrome (Trisomy 21), Trisomy 18, and Trisomy 13 when combined with maternal blood tests.
Twin Pregnancy Assessment
Determines chorionicity and amnionicity, which are important factors in managing twin pregnancies and identifying potential complications.
Early Structural Assessment
Examines the developing brain, spine, limbs, abdominal wall, heart position, stomach, bladder, and other major fetal structures.
Fetal Growth and Viability
Confirms heartbeat, assesses crown-rump length (CRL), and evaluates appropriate growth of both fetuses.
Multiple Pregnancy Monitoring
Identifies early complications such as growth discordance, vanishing twin syndrome, or other abnormalities requiring specialist follow-up.
Who Should Consider this Scan?
Your doctor may recommend a USG OBS NT-NB with Twins scan if you:
- Are pregnant with twins
- Are between 11 and 13 weeks 6 days of pregnancy
- Require first-trimester chromosomal screening
- Need confirmation of chorionicity and amnionicity
- Have a family history of genetic disorders
- Conceived through assisted reproductive techniques such as IVF
- Require detailed early pregnancy assessment
Benefits of USG OBS NT-NB with Twins
- Safe, non-invasive, and radiation-free
- Evaluates both fetuses individually
- Screens for chromosomal abnormalities
- Determines chorionicity and amnionicity
- Detects early structural abnormalities
- Assesses fetal growth and viability
- Supports early pregnancy management
- Helps plan appropriate antenatal care for twin pregnancies

Test information: No preperation needed.
Reporting: Within 01 hour*
- No fasting is required for this scan.
- A moderately full bladder may be recommended, especially during early pregnancy or for a transabdominal examination. Please follow your doctor's instructions.
- Wear loose and comfortable clothing for easy access to the abdomen.
- Carry all previous pregnancy ultrasound reports, blood test reports, antenatal records, IVF records (if applicable), and your doctor's referral.
- Continue taking your prescribed medications, including prenatal vitamins, unless advised otherwise by your doctor.
- Inform the radiologist about your last menstrual period (LMP), expected due date (EDD), previous pregnancy complications, or any history of genetic disorders.
- If you are carrying twins through IVF or other assisted reproductive techniques, inform the radiologist before the examination.
- Arrive at the centre 15–20 minutes before your scheduled appointment.
