What Is Ultrasound? (Sonography)

Ultrasound during pregnancy is a technique through which images of the unborn baby’s development are produced through high-frequency sound waves. It is also used to create pictures to check the pelvic health of the mother undergoing the procedure.

How an Ultrasound is Performed?
The pregnant women must lie on their backs on an examination table.
A gel is spread on the belly of the mother, and a transducer is run over the gel. This transducer generates sound waves on the mother’s belly through which pictures are drawn onto the monitor.
The images are then examined by medical professionals.
There are various ways of performing an ultrasound in pregnancy.
One of the ways is to create images of the vagina to see the position of the baby (head-on or breech). The length of the cervix is also measured by this method of conducting the ultrasound.

When and How Often do you Need an Ultrasound?
Routine pregnancies require fewer ultrasound sessions. However, high-risk pregnancies may require a greater number of ultrasound sessions than the usual number. Women with a normal foetus should undergo their ultrasound sessions during the second trimester of their pregnancy.

However, an ultrasound session can take place as early as 6–8 weeks into the pregnancy. Additionally, an early pregnancy ultrasound takes place with the help of a transvaginal transducer. This transducer gives your doctor an early and fair idea of the baby’s growth. Moreover, a transvaginal ultrasound is the first ultrasound in a pregnancy. The first ultrasound during pregnancy reveals a lot of valuable information to the doctor, such as the heartbeat of the unborn baby, the due date of the baby, the number of fetuses attached to the uterus of the baby, and the location of the baby (to close out any chances of an ectopic pregnancy, which is majorly detected by an ectopic pregnancy ultrasound). Most pregnancies involving healthy women ideally require two pregnancy scans. One is during the first trimester to ensure the due date of the baby, and the other one is during the second trimester at 18–22 weeks to check the anatomy of the unborn child. The early pregnancy scan is highly beneficial for the mother for the reasons mentioned above. This kind of ultrasound is also known as a first trimester ultrasound.
