NT Scan – Early Pregnancy Screening for Chromosomal Abnormalities
At Akshar Imaging Centre, we provide advanced NT Scan in Ahmedabad to assess the health and development of your baby during early pregnancy. This non-invasive, radiation-free ultrasound measures the nuchal translucency — a fluid-filled space at the back of the baby’s neck — between 11 and 14 weeks of gestation, helping doctors evaluate the risk of chromosomal abnormalities such as Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), and Patau syndrome (Trisomy 13).
Our expert radiologists use high-resolution ultrasound systems to perform this crucial first-trimester screening, providing accurate measurements and insights for early risk assessment.
What Is an NT Scan?
A Nuchal Translucency (NT) Scan is a specialized prenatal ultrasound that measures the thickness of the fluid at the back of the fetus’s neck. Increased thickness may indicate a higher risk of chromosomal abnormalities, congenital heart defects, or other genetic conditions.
The NT Scan is usually combined with a first-trimester blood test to improve accuracy in assessing the risk of chromosomal disorders. It is a safe, painless, and non-invasive procedure suitable for all expectant mothers.
Why It’s Performed / Common Indications
- Early detection of chromosomal abnormalities (Down syndrome, Edwards syndrome, Patau syndrome)
- Assessment of congenital heart defects
- Evaluation of risk in mothers over 35 years of age
- First-trimester screening in combination with maternal blood tests
- Early reassurance of normal fetal development
Preparation
- No fasting or special preparation is required.
- Arrive with a full bladder, as it may help improve visibility of the fetus.
- Wear loose, comfortable clothing.
- Inform the technologist about any previous ultrasound scans or medical conditions.
Procedure
- You will lie on the examination bed, and a water-based gel is applied to your abdomen.
- The radiologist gently moves the transducer over your belly to capture high-resolution images of the baby.
- The nuchal translucency measurement is taken carefully between 11–14 weeks of pregnancy.
- The scan is painless, safe, and usually takes 15–20 minutes.
What Happens Next (Interpretation)
- Thickness of the nuchal translucency at the back of the fetal neck
- Crown-rump length (CRL) to confirm gestational age
- Basic fetal anatomy and growth
- Risk assessment for chromosomal abnormalities
A detailed report is prepared and shared with your obstetrician to guide further testing or reassurance.
Benefits vs. Risks
- Benefits: Early detection of risk for chromosomal abnormalities, non-invasive and radiation-free, helps plan further tests, and provides reassurance about early fetal development.
- Risks: No known risks; safe for both mother and baby. Only a screening test — further tests may be advised for confirmation.

Frequently Asked Questions (FAQs)
1. Is the NT Scan safe during pregnancy?
Yes, it is completely safe and uses no radiation.
2. When should I get an NT Scan?
Between 11 and 14 weeks of pregnancy for accurate measurements.
3. How long does the scan take?
Usually 15–20 minutes.
4. Do I need to have a full bladder for the scan?
Yes, a moderately full bladder helps improve visibility of the fetus.
5. Does an abnormal NT scan mean my baby has a problem?
No, it only indicates increased risk. Further tests like NIPT, CVS, or amniocentesis may be advised for confirmation.
