The Ultrasonography is used in pregnancy to detect the health of the mother and the timing and development of the foetus which is growing in the womb of the mother. This is considered as safe, accurate and cost effective. This is a tool where, sound waves are used to create visual images and a continuous movement of the foetus can be seen in a monitor screen. A full bladder is recommended for the procedure when abdominal scanning is done. Your lower abdominal area is exposed and you required to wear a loose cloth for this. A little discomfort is felt because of the fullness of the bladder and also the gel applied though it is non staining, but you may feel slightly cold and wet.
A recent study suggests, a pregnant woman should have regular ultrasound between 18 weeks to 22 weeks of her pregnancy to confirm the timings. This also helps to detect any abnormality in the developing foetus.
Doppler ultrasound study is also a part of obstetrical ultrasound examination. This is a special technique which allows the doctor to see the blood flow through arteries, abdominal veins, neck, legs, arms and brain of the foetus and he/she can evaluate the blood flow to the liver of kidney.
Obstetric ultrasound helps the doctor to evaluate the following:
Connecting the presence of a living embryo/foetus
To estimate the age of the pregnancy
Evaluating the position of the foetus
Assessment of the foetal growth
Assessing the foetal well being
To evaluate the presence of multiple pregnancies
Judgement of Amniotic fluid around the foetus
Congenital abnormalities if any in the foetus
Once the ultrasound is over, a radiologist will evaluate the findings and will be sending a signed report to the doctor. Based on this report your doctor will suggest you for further examination date. A regular examination is mandatory and follow as per your doctors advice.
