Ultrasound Scanning and Pregnancy go hand-in-hand. In India, from confirming the pregnancy to checking the cord around the baby’s neck, ultrasound scans play a major role in ensuring the health of the baby inside the womb. A minimum of 4 scans ( Positive pregnancy confirmation scan, NT scan, Anomaly scan and Third trimester MBPP scan) are taken in most of the hospitals in India. However, in countries like the United States, the number of scans taken are comparatively less (two or three).
After a positive result from HPT (Home Pregnancy Test), the pregnancy confirmation scan is done, in order to ensure that you are really pregnant. The heartbeats can be clearly witnessed in this scan. So, this will be the scan that makes us all set to celebrate the onset of pregnancy and parenthood vibes. 💕
The second scan is the NT (Nuchal Translucency) scan, which assesses the baby’s risk of developing Down’s syndrome and similar chromosomal abnormalities. The scan must be taken between 11 and 14 weeks of pregnancy, when the baby’s neck is transparent. It is said by the doctors that, though the NT test is 98% accurate, women who get a positive result would still need CVS (Chorionic Villus Sampling) or Amniocentesis for a sure diagnosis.
The third scan is taken during the end of fifth month pregnancy. As the name suggests, the Anomaly scan is done to find out if there are any major anomalies / physical abnormalities in the baby’s body. Again, not all the minor details can be captured at this stage, it is done only to check for the ‘major’ anomalies.
Third trimester MBPP (Modified BioPhysical Profile) scan mainly assesses the baby’s growth and amniotic fluid rate.
The four components – Fetal posture & tone, fetal movements, fetal breathing movements and quantitative amniotic fluid volume are measured and rated for a maximum score of 2 for each one. An abnormality in a component means that the score would be 0 points for that particular component.
Depending on further necessities, more scans may be taken by the doctor, to get into firm conclusions.
