USG test in pregnancy is a very useful tool to look for baby’s development, multiple pregnancies, anomalies in baby and many other multitudes of things. It is a painless, noninvasive and safe test which can very accurately detect various anomalies in the baby. It uses high-frequency sound waves to study the various internal body structures. These sound waves are sent inside the body via a probe or transducer and then they are reflected back by various tissues in a different manner. These echoes are shown as an image on the screen.
Uses of Ultrasound Scans During Pregnancy-
During pregnancy 3-4 USGs are done in various stages of development of the baby. In pregnancy, you do not need to come empty stomach unless specially instructed to do so.
It is a very useful diagnostic technique for various anomalies in the baby. But not all 100% anomalies can be detected on USG and if any anomaly is detected, further tests are needed to confirm the same.
What to expect while going through a pregnancy scan?
A pregnancy scan can be of 2 types:
After the procedure, the gel is wiped clean and you can go to the toilet. It has practically no complications to either you or the baby so you can go for a scan without any worry. If any anomaly is detected, you may be advised to go for further tests like CVS or amniocentesis.
With the advent of 3D and 4D machines, the birth of an anomalous baby has become very rare as anomalies are detected in pregnancy itself and taken care. So you should follow the advice of your doctor and get your scans done on time so that you are saved of any problems later on.
