What is Anomaly Scan?

The scan aims to look if everything to this period is not having any major physical abnormalities in the growing baby. This scan is viewed as a dating scan where a greyscale 2-dimensional (2-D) image is produced which gives the side-view of the little baby that is all the way carried all the way by mom and is growing in the bump of the mother. This image describes the baby’s face and hands in early weeks and gives the consult doctor and specialist an accurate vision of what is going inside. This can be undoubtedly super exciting as first time parents are getting a visual of their upcoming new born baby!

Why is Anomaly Scan done?

The anomaly also known as mid-pregnancy is done for keeping an eye if the baby is facing any physical problems in the growing stage. Although the scan can obviously  not reveal every problem, instead it gives an accurate overall idea about the baby’s body parts as heart beat rate, brain development, spinal bone, face structure, kidneys, abdomen parts it also allows the sonographer to identify the conditions whether everything is going right.

Mostly the scan proves that the baby is growing in the right way, but in a few cases, the expert may find a problem.

How is it done?

A specialised sonographer asks the patient to lay down on a couch and uncover the abdomen and apply gel on the abdomen.Then he/she passes a small ultrasound probe over the skin of the abdomen to examine the baby’s body and to check whether everything is going in the right way or not. The ultrasound gel is applied on the skin  to make sure there is proper contact between the probe and the skin. As the probe moves, a grayscale 2-D image of the baby will appear on the screen. For a better scan, the sonographer will advise the patient to have a full bladder before the scan. At times the sonographer may apply slightly more pressure on the stomach to see a better view of the baby.

An ultrasound examination of your pregnancy is mandatory and highly recommended  at 19-20 weeks gestation.

At this stage the scan can confirm:

  • Confirm that the small baby’s heart is beating
  • Detect multiple pregnancies in order to check the health status of the baby
  • Measure the fetal size as per 20 week baby scan 
  • Assess the position of the placenta which can help to see that baby’s growth all parts are safe and no internal injuries are recorded
  • Check the volume of amniotic fluid around the baby so that the diet is given properly and the baby can grow to its full capacity.
