What Is a Growth Scan?

A growth scan in pregnancy is an ultrasound examination that helps monitor the growth and development of the fetus. This type of scan is an important tool for ensuring the health and well-being of both the mother and the baby. In this blog post, we will cover the purpose, timing, and process of growth scans, as well as the information obtained from them and the factors that can impact fetal growth.

Why Do I Need a Growth Scan?

Growth scans are performed to track the growth and development of the fetus throughout pregnancy. They help determine if the baby is growing at a normal rate and check for any potential issues that may affect the health of the mother or baby.

Growth scans are usually performed between 24 to 32 weeks of pregnancy and then again between 36 to 40 weeks of pregnancy. However, in some cases, additional scans may be recommended if the ultrasound doctor suspects any potential problems.

Process Of a Growth Scan

The following is a detailed step-by-step guide to the process of a growth scan:

Preparation: Before the scan, you will be asked to lie down on an examination table and expose your belly. You may also be asked to drink water and not empty your bladder to help improve the visibility of the fetus during the scan.
Ultrasound Gel: The radiologists will apply a special gel to your abdomen, which helps to conduct the ultrasound waves.
Transducer placement: The sonographer will then place a transducer, which is the handheld device that sends and receives ultrasound waves, onto your belly.
Measurement of the fetus: The sonographer will measure the size of the fetus, including the head circumference, abdominal circumference, and femur length. This information is used to determine the fetal weight and assess if the baby is growing at a normal rate.
Checking for abnormalities: The sonographer will also check for any abnormalities or problems, such as a low level of amniotic fluid or a problem with the placenta.
Examination of the fetus: The sonographer will examine the fetus for any signs of distress, such as reduced movement or abnormal heart rate.
Images and recordings: The sonographer will take images and recordings of the fetus, which will be used to create a detailed report of the results.
Final check: The sonographer will perform a final check of the fetus to ensure that all necessary measurements have been taken and that there are no concerns.

Information Obtained from a Growth Scan

There are many factors that can influence fetal growth, including the mother’s health, the amount of amniotic fluid, and the presence of any medical conditions such as gestational diabetes. The information obtained from a growth scan helps determine if the fetus is growing at a normal rate and checks for any potential issues that may affect the health of the mother or baby. This information can also help predict the due date and determine the position of the fetus in the womb.

Motherhood India hospitals are well-equipped to provide comprehensive prenatal care, including growth scans. We have state-of-the-art facilities and equipment, and highly skilled sonographers and obstetricians to perform growth scans. These scans are performed in a safe and comfortable environment and provide expectant mothers with valuable information about the health and well-being of their baby.

Benefits of Growth Scans

Growth scans are an important tool for monitoring fetal well-being and ensuring the health and safety of both the mother and baby. They provide valuable information about the growth and development of the fetus and help identify any potential problems early on. A few benefits include:

Fetal weight estimation: A growth scan provides an estimate of the fetal weight, which is important for determining if the fetus is growing at a normal rate. This information can also help identify if there is a need for further tests or interventions if the fetus is not growing as expected.
Detection of growth abnormalities: A growth scan can detect if there are any growth abnormalities, such as low birth weight or macrosomia (excessive birth weight). This information can help inform decisions about delivery and potential complications.
Monitoring fetal well-being: A growth scan provides important information about the health and well-being of the fetus, such as the position of the fetus and the level of amniotic fluid. This can help detect potential problems such as a reduced fetal movement and help provide early intervention if necessary.
Detection of structural abnormalities: A growth scan can detect structural abnormalities, such as cleft lip, spinal cord defects, and heart problems. Early detection of these abnormalities can help inform decisions about prenatal care and delivery planning.
Improved prenatal care: A growth scan can help inform prenatal care by providing important information about the growth and development of the fetus. This information can be used to develop a customized care plan for both the mother and the fetus, which can help optimize the health and well-being of both.

Interpretation of Growth Scan Report

The growth scan report is interpreted by a gynecologist. If the results indicate that the fetus is not growing at a normal rate, further tests and scans may be recommended to determine the cause and determine the best course of action. It is important to continue to attend all recommended prenatal appointments to ensure the health and well-being of both the mother and baby.

Conclusion

In conclusion, growth scans during pregnancy are an important tool for monitoring the growth and development of the fetus. They provide valuable information about the health and well-being of both the mother and the fetus.

Frequently Asked Questions About Growth Scans

Which week is best for a growth scan?

Doctors commonly recommend a growth scan during the third trimester when they need to assess fetal size, estimated weight or growth progression. The exact week depends on the pregnancy and the reason for the scan. Some women may have a growth scan around 28, 30 or 32 weeks, while others may need one later in pregnancy or more than one scan for comparison.

What does a growth scan report show?

A growth scan report usually includes fetal measurements such as head circumference, abdominal circumference and femur length. It may also include estimated fetal weight, amniotic fluid, placental findings and fetal position. Doctors interpret these findings together rather than relying on one measurement alone.

What does estimated fetal weight mean in a growth scan?

Estimated fetal weight, or EFW, uses ultrasound measurements to estimate the baby’s weight. It does not provide an exact weight. Doctors use EFW together with growth percentiles, previous scans and other findings to understand whether the baby continues to grow as expected.

Is Doppler always part of a growth scan?

No. A standard growth scan does not always require Doppler assessment. Doctors may add Doppler when they need more information about blood flow through the placenta, umbilical cord or fetal circulation, especially when they have concerns about fetal growth or placental function.

What if the baby measures smaller than expected on a growth scan?

A smaller measurement does not automatically mean that the baby has a growth problem. Some babies are naturally smaller. Your doctor may review the overall growth pattern, estimated fetal weight, abdominal circumference, amniotic fluid and Doppler findings and may recommend another scan after an appropriate interval.

How many growth scans are needed during pregnancy?

There is no fixed number for every pregnancy. Some women may need one growth scan, while pregnancies with maternal medical conditions, suspected fetal growth restriction or previous scan findings may require serial scans. Your obstetrician will decide the frequency based on clinical need.
