Importance of Ultrasound Scans during Pregnancy

Updated: Apr 16, 2022

Ultrasound (Sonography) is an imaging modality that uses sound waves of different frequencies to create a picture of the human organs. With increased accessibility, Ultrasound or Sonography has become the most used diagnostic procedure in Obstetrics and Gynecology.

It can provide very important diagnostic information about a developing baby, such as confirmation of pregnancy and gestational age, Checking for multiple pregnancies, birth defects and/or placental problems, Monitor fetal location, fetal growth, and amniotic fluid levels. And also support for other tests.


Different Types of Ultrasound in Pregnancy

Abdominal ultrasound - Most commonly done where a transducer is moved across the belly which captures the black and white images onto the Ultrasound screen.

Transvaginal ultrasound - In this, a small probe is inserted into the vagina. It is most commonly used in early pregnancy and can also be done if trans-abdominal sonography does not provide sufficient information.

3-D ultrasound - Visualization of width, height, and depth of the fetus and reproductive organs is done.

4-D ultrasound - The movement of the baby can be recorded.

Fetal echocardiography - To check for fetal heart defects.

How Many Ultrasounds Are Required During Pregnancy And Are There Any Risks?


The number of sonograms and timing may differ from woman to woman depending upon certain health conditions and while it is considered safe for both baby and fetus as it uses sound waves rather than radiation (in X-rays), it is still advised to expose the pregnant female to USG as low as reasonably advised (Alara Principle).

Ultrasound is, arguably, the most frequently used diagnostic procedure in obstetrics. It is appropriate, painless, yields immediate, extensive results, and is broadly considered to be safe. The common belief exists that diagnostic ultrasound (DUS) does not produce any risk to the pregnant patient or to her fetus.
