USG in pregnancy stands for ultrasonography, which is a common and safe imaging technique used to monitor the health and development of the baby during pregnancy. It is a non-invasive, painless procedure that uses sound waves to create images of the baby, placenta, and other structures in the uterus.
Why is Ultrasound Used During Pregnancy?
Ultrasound scans serve several important purposes during pregnancy, including:
- Checking Baby's Development: Ultrasounds allow doctors to assess the baby's growth and development throughout the pregnancy.
- Detecting Multiple Pregnancies: Ultrasounds can confirm if you are carrying twins, triplets, or more.
- Identifying Potential Abnormalities: While not 100% accurate, ultrasounds can help identify potential abnormalities in the baby's development. According to information provided, "the ultrasound scan isn't 100 per cent accurate, but the advantages of the test are that it's non-invasive, painless and safe for both mother and unborn baby."
- Determining Gestational Age: Ultrasound can help accurately determine how far along you are in your pregnancy, especially in early stages.
- Evaluating Placenta: Ultrasound is used to check the position and condition of the placenta.
- Assessing Amniotic Fluid Levels: Measuring amniotic fluid helps in determining the baby's well-being.
Types of Ultrasounds in Pregnancy
Different types of ultrasound may be used depending on the stage of pregnancy and the information needed:
| Type of Ultrasound | Description |
|---|---|
| Transabdominal | The most common type, where a transducer is moved over the abdomen. |
| Transvaginal | A probe is inserted into the vagina, providing a clearer image in early pregnancy. |
| 3D Ultrasound | Creates a three-dimensional image, helpful for detailed examination of fetal structures. |
| 4D Ultrasound | Shows a live, moving three-dimensional image, allowing you to see the baby's movements in real-time. |
| Doppler Ultrasound | Measures blood flow in the baby's blood vessels, umbilical cord, and uterus. |
