What is meant by NT?
Nuchal translucency ( NT ) is the sonographic appearance of a collection of fluid under the skin behind the fetal neck in the first-trimester of pregnancy. The term translucency is used, irrespective of whether it is septated or not and whether it is confined to the neck or envelopes the whole fetus.
What is a normal NT?
What is a normal nuchal translucency measurement? An NT of less than 3.5mm is considered normal when your baby measures between 45mm (1.8in) and 84mm (3.3in). The NT usually grows in proportion with your baby.
What does nt mean in ultrasound?
Nuchal translucency ( NT ) is the normal fluid-filled subcutaneous space between the back of the fetal skin and the overlying skin. NT is visible and can be measured by ultrasonographic imaging between 11 weeks and 14 weeks gestation. Increased NT is associated with different fetal chromosomal and nonchromosomal
What is a normal NT measurement at 12 weeks?
First trimester measurement of NT at 12 weeks of gestation was 3.2 mm during the routine first trimester screening. The normal range of NT for this age is 1.1-3 mm.
What is abnormal NT?
Introduction. Nuchal Translucency ( NT ) is the sonographic form of subcutaneous gathering of liquid behind the foetal neck in the first trimester of pregnancy. There is association of increased NT with chromosomal and non-chromosomal abnormalities.
Which week is best for NT scan?
The ultrasound scan (called a nuchal translucency ), is best done at 12 weeks of pregnancy but can be done any time between 11 weeks and 2 days and 13 weeks and 6 days of pregnancy. If you are 14 weeks pregnant or more when you decide to have screening, you will be offered Second Trimester Maternal Serum Screening.
Can we identify gender in NT scan?
There were no relations between fetal gender and FHR and also NT. Conclusions: Gender can be detected with great accuracy in gestations between 11 to 13 weeks and 6 days by using AGD.
What happens if NT scan is not normal?
What Happens If I Have Abnormal NT Ultrasound Results? The first thing to do is remain calm. An abnormal test result is a statistical likelihood, not a concrete diagnosis. Talk to your doctor about additional testing options if chromosomal abnormalities are present.
Is NT scan painful?

What is percentile in NT scan?
The reference 95th percentile value range for NT was 1.8-2.35 and increased NT thickness according to our obtained values was associated significantly with chromosomal abnormalities.
How accurate is NT scan?
How accurate is the NT scan? The NT scan alone will detect about 70 to 80 percent of babies with DS (depending on which study you look at). The detection rate for the NT scan plus a first-trimester blood test ranges from 79 to 90 percent.
How much does NT scan cost?
The approximate cost of the NT scan in India is around 600 INR to 4000 INR. This cost variation depends upon the city, fees of the doctor, overall medical condition of the patient, type of the hospital and many other factors.
What checks are done at 12 week scan?
It involves a blood test and measuring the fluid at the back of the baby’s neck (nuchal translucency) with an ultrasound scan. This is sometimes called a nuchal translucency scan. The nuchal translucency measurement can be taken during the dating scan.
What is a low risk NT measurement?
A very small nuchal translucency measurement – less than 2.5 mm – places the pregnancy in a low – risk group for problems, such as fetal heart abnormalities.
Can you see abnormalities at 12 week scan?
