Ultrasound in Pregnancy – Tracking Baby’s Growth

Being a parent is the dream of many couples and individuals. And nothing makes this journey more pleasant than seeing the growth of your baby. Now, there are many methods to monitor your baby’s growth inside your womb. Among many methods, one of the best and most effective ways is to use ultrasound. Not only does ultrasound allow you to monitor your baby’s growth in decent quality, but it is also affordable as well. But saying this is just scratching the surface. The specifics are a bit more complicated than this. However, before we even discuss the specifics of ultrasound in pregnancy, what is it?

Well in this blog, we shall explore these exact aspects. Here, we cover what an ultrasound in pregnancy is, the types of pregnancy ultrasounds, the types of ultrasound scans offered during pregnancy, and what happens during the scan. We also cover what can be detected in a pregnancy ultrasound and why you may need an ultrasound during pregnancy. So, keeping this in mind, let’s get started!

What Is An Ultrasound In Pregnancy?

ultrasound-pregnancy

In simple terms, an ultrasound or sonogram for short, is a test during the pregnancy designed to check the health and development of your baby. In this process, the nurse midwife, obstetrician, or sonographer performs the ultrasound during the pregnancy. Now, the specific reasons for this vary depending on your circumstances, including checking the health of the baby in general or to see if there are any problems for the baby.

In this process, the sound waves are sent through the abdomen or vagina through a device known as a transducer. The device then bounces off the structures inside your body which includes your baby and reproductive organs. The sound waves are then converted into images so that the users can see what is inside the organs. Now, unlike X-rays, ultrasound does not use radiation but rather just waves of sound. Therefore, it has minimal risk attached to it. That said, although the risks are minimal, you should only take this check when recommended and medically necessary.

If you take the ultrasound during the prenatal phase, it can be known as a fetal ultrasound or pregnancy ultrasound. You shall know the specific time for when to take the ultrasound during pregnancy based on your health industry.

Types Of Pregnancy Ultrasounds

So now you know the basic gist of what an ultrasound is. But do you know that there are different types of ultrasound in pregnancy? Yes, depending on the specifics of your circumstances, the doctors can use a different form of ultrasound in pregnancy. So, what are these different types of ultrasound? Some of the key types of ultrasound in pregnancy include:

1. Transvaginal ultrasound

This form of ultrasound essentially involves inserting a small probe into the vagina. The inserted probe then emits an ultrasound to provide a clear image of the uterus, ovaries, and developing baby. It is especially used in early pregnancy.

2. 3-D ultrasound

As its name suggests, this form of ultrasound creates three-dimensional images of the things inside the uterus. This includes the 3D images of the fetus as well and it offers a more detailed view of its development. 3D ultrasound is used to check for abnormalities inside the baby or provide you with a realistic view of the baby.

3. 4-D ultrasound

From the name of this form, you can easily guess that  4-D ultrasound is a step up from our previous entry. The 4-D ultrasound allows you to see the live and moving images of the baby. This essentially means that you can see how your baby is doing or acting inside your womb in real time, although with some limitations of the ultrasound technology.

4. Fetal echocardiography

The final form of ultrasound in pregnancy is the fetal echocardiography, and it is focused on the baby’s heart. This form of ultrasound provides detailed images that allow you to check the structure of the baby’s heart and is typically used when the experts suspect a heart condition.

Although there are many other types of ultrasound in pregnancy, the ones we mentioned here are just some of the key ones. For detailed information, do contact the associated expert.

Ultrasound Scans Offered During Pregnancy

Now, at this point, you are already aware of the different types of pregnancy ultrasounds. But what about the specific ultrasound scans offered during pregnancy? Well, the specific ultrasound offered during pregnancy depends on your individual circumstances. That said, we can provide you with a general list of specialized ultrasounds offered during pregnancy. Some of these include:

1. Dating scan

Dating ultrasound is typically performed during early pregnancy at around six to nine weeks. The primary purpose of this ultrasound is to confirm the pregnancy and calculate the estimated due date (EDD) based on the size of the baby and its development. The scan is especially useful for you if you are a woman with irregular menstrual cycles or uncertain conception dates. Additionally, the dating scan is also used to confirm whether it is a single or multiple pregnancy and check the general health of the uterus and the surrounding reproductive structures.

2. Nuchal translucency scan

Following the dating scan, we have a nuchal translucency scan, which is conducted between 11 and 14 weeks of pregnancy. The NT scan is part of the first-trimester screening for chromosomal abnormalities, such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and Patau syndrome (trisomy 13). In this scan, the thickness of the fluid-filled space at the back of the baby’s neck is measured. This is combined with the maternal blood test and other factors such as age, and it provides risk assessment for certain conditions. It also offers the chance to observe the baby’s early development, such as heartbeat and basic anatomical features.

3. Anomaly Scan

Also known as a mid-pregnancy or 20-week ultrasound scan, an anomaly scan is another form of detailed ultrasound scan that is performed during the pregnancy. As its name suggests, this scan is typically performed between 18 to 22 weeks of gestation. The key purpose of anomaly scans is to check for any forms of structural abnormalities within the baby. Some of the key things that anomaly scan checks within the baby include:

  • Baby’s anatomy:
    • Head, brain, spine, and skull
    • Heart structure and function
    • Face, including the lips (to rule out cleft lip)
    • Abdomen, including stomach, kidneys, bladder
    • Limbs and fingers
  • Amniotic fluid level
  • The position of the placenta and umbilical cord
  • Growth of the baby

As you can guess, it is a routine scan which is offered for most pregnant individuals. Do note that the findings of the anomaly scan help the experts decide if they need further tests or interventions.

4. Morphology scan

The final type of ultrasound scan for pregnancy we have is the morphology scan. It is generally performed between eighteen and twenty-two weeks (18 – 22) weeks and it offers the baby’s anatomy. The scan evaluates the development of major organs and systems, which include the brain, spine, heart, kidney, and limbs. This scan can detect structural abnormalities, examine the position of the placenta, and measure the amniotic fluid levels. You can also technically find the sex of the baby during this scan, although you do have to note that finding the sex of the baby is illegal in many parts of the world. Needless to say, the morphology scan is one of the most detailed scans during the pregnancy as it offers critical insights into the baby’s health and development.

What Will Happen At The Scan?

ultrasound-imageThe specific activities that occur depend on the specific type of ultrasound you use. That said, we can provide you with a general outline of the events surrounding the ultrasound scan. So, keeping this in mind, the following are key events you can expect during the scan.

I. Before the Scan

When you arrive at the organization, the sonographer can ask you a few questions about your pregnancy. The questions can include your last menstrual period and previous scans. You may also be asked to have a full bladder, depending on the specific types of scans, as it aids in giving clearer images, especially during early pregnancy. Once all the preparation is done, the experts then apply a small amount of gel to your abdomen. If you are going for a transvaginal scan, the experts insert a small special probe.

II. During the Scan

As the scan progresses, the experts ask you to lie comfortably in the examination bed. They then use a handheld device called a transducer. If you are going for an abdominal scan, the experts move the transducer gently over your belly as they send high-frequency sound waves into your belly. These waves are then reflected back to create detailed images of your baby and reproductive structures on a screen.

On the other hand, if you need a transvaginal scan, the experts insert a small probe into the vagina, which gives more accurate images. Although it can be a bit weird and somewhat of an uncomfortable feeling, it should not be painful. If it does feel painful, contact an expert immediately.

Depending on the type of scan you use, you can see a live image of your baby on the screen and/or specific details such as heartbeat and facial expressions.

III. After the Scan

The final phase only takes roughly 20 to 40 minutes. After you are done with the ultrasound during pregnancy, the experts provide you with an overview of the findings and can print images for you. They then send a detailed report to your healthcare provider, who then discusses the results with you during your next appointment.

What Can Be Detected In A Pregnancy Ultrasound?

If you have read till this point, you should already have a decent idea regarding what ultrasound in pregnancy is; you should already have a general idea regarding what this process can detect. But now, let’s take a specific look at the things that can be detected in a pregnancy ultrasound scan. Some of these key things include:

  • Confirmation of Pregnancy: The first thing that the ultrasound detects is pregnancy. If you are in the early phase of the pregnancy, it detects whether or not you are pregnant, the baby’s heartbeat (if you are pregnant), and verifies if you are pregnant with one or more babies.
  • Gestational Age and Due Date: Alongside confirming the state of pregnancy, ultrasound is also used to estimate how far along the pregnancy is. It is also used to calculate the accurate due date.
  • Baby’s Development: Ultrasound is also used to monitor the growth and development of the baby and ensure that it is progressing as expected. It can also detect the milestones such as limb formation, organ development, and overall growth patterns.
  • Structural Abnormalities: Detailed ultrasound scans can also be used to detect structural issues with the baby’s organs and tissues. Some of the detected abnormalities include neural tube defects such as spina bifida and congenital heart defects.
  • Placenta and Amniotic Fluid: Ultrasound is also used to detect the amount of amniotic fluids. This is because too much or too little fluids can indicate potential issues with the pregnancy.
  • Fetal Well-being: Ultrasounds at the later stages can also be used to detect the overall health of the baby and the baby’s movements, breathing and position as the due date approaches.
  • Detection of Chromosomal Conditions: Specific ultrasound scans such as nuchal translucency scan can detect risks of chromosomal abnormalities such as Down syndrome, Edwards syndrome, and Patalu syndrome. These detections can then be supplemented with blood tests for tests if required.
  • Pregnancy Compilations: Depending on the specific type of scan used, ultrasound can also be used to detect specific complications such as ectopic pregnancy, molar pregnancy, and intrauterine growth restrictions.
  • Position of the Baby: Lastly, ultrasound can also be used to confirm if the baby is in the correct position for delivery or not. Depending on the position, the doctors can then determine if you need surgical intervention or not.

Understanding Pregnancy Ultrasound Results

Now that you know what the ultrasound can detect, you may want to know how to know what is detected in the results. Well, the specific way to understand the pregnancy ultrasound results depends on the results itself. That said, there are a few common aspects that you can check for in the pregnancy ultrasound results.

  • Measurements and Growth: This measures the baby’s size to ensure that they are growing at a healthy rate. Some of the key measurements here include:
  • Crown-Rump Length: Used in early pregnancy to estimate gestational age.
  • Biparietal Diameter (BPD), Head Circumference (HC), and Abdominal Circumference (AC): Evaluate growth in mid-to-late pregnancy.
  • Femur Length (FL): Assesses the baby’s skeletal growth.
  • Heartbeat and Movements: A long, steady heartbeat is a positive sign, while decreased activity is a negative sign.
  • Amniotic Fluid Levels: Too much fluid (polyhydramnios) or too little (oligohydramnios) could indicate potential complications.
  • Placental Position: If the results show conditions such as placenta previa (where the placenta blocks the cervix) or placental abruption, then you need additional interventions, and if not, then you can proceed with regular activities.
  • Baby’s Position: This aspect shows whether the baby is head down (cephalic), breech, or in another position.
  • Detection of Anomalies: The scan also detects if there are any structural abnormalities such as neural defects, heart issues, or cleft lips.
  • Risk Assessment: Results from specific scans, like the nuchal translucency test, provide a risk score for chromosomal abnormalities.

Why Additional Ultrasounds May Be Needed During Pregnancy

So after looking at the things to check in an ultrasound results, you might think – is this enough? Well, depending on specific circumstances, one ultrasound may not be enough. So the question here is, when are the circumstances where additional ultrasounds may be needed during pregnancy? Well, some of the circumstances when you might need additional ultrasounds during pregnancy include:

  • When the baby is measuring small or large for their gestational stage, additionally, a second ultrasound might also be required if there is a risk of Intrauterine Growth Restriction. 
  • When there are issues with the placenta, the conditions can be anything ranging from placenta previa to placental abruption.
  • When you are having multiple pregnancies such as multiple pregnancies with twins, triplets, or more. 
  • When your cervix is shorter than expected.
  • When you have a history of preterm birth.
  • When you have medical conditions such as gestational diabetes or preeclampsia.
  • When you experience bleeding or cramping early in the pregnancy.
  • When you have had complications in previous complications. 
  • When you have specific medical conditions which can affect your pregnancy. 

This is by far not an exhaustive list of all the circumstances where you might need additional ultrasound. Regardless, we hope you found the general gist of it all.

FAQ Ultrasound in Pregnancy: How It Monitors Baby’s Growth

Q1. In which week of pregnancy ultrasound should be done?

The first ultrasound, called a dating scan, is usually done around 6 to 9 weeks to confirm the pregnancy and calculate your due date. Another important scan, the nuchal translucency scan, is done at 11 to 14 weeks. After that, most women have a detailed anatomy scan around 18 to 22 weeks to check the baby’s development.

Q2. What are 5 warning signs of a possible problem during pregnancy?

Look out for severe abdominal pain, heavy bleeding, sudden swelling in the hands or face, reduced baby movements, or a high fever that doesn’t go away. These symptoms could indicate complications like preeclampsia, miscarriage, or infection. Always contact your healthcare provider if something feels off—it’s better to be cautious.

Q3. How many weeks pregnant can an ultrasound detect?

An ultrasound can detect a pregnancy as early as 4 to 6 weeks. At this stage, you might only see the gestational sac or a tiny embryo. By 6 to 7 weeks, the baby’s heartbeat can often be detected as well.

Q4. Can an ultrasound scan harm my baby?

No, ultrasound scans are considered safe and don’t harm your baby. They use sound waves, not radiation, to create images. Doctors recommend them only when necessary to ensure your pregnancy is progressing well.

Q5. How much does an ultrasound cost?

The cost of an ultrasound varies depending on where you live and the type of scan. In most cases, it ranges from NPR 2000 to NPR 10,000. Check with your healthcare provider or insurance to understand coverage and costs.

Q6. How many ultrasounds do you have when pregnant?

Most women have about 2 to 3 ultrasounds during a routine pregnancy: a dating scan, a nuchal translucency scan, and a detailed anatomy scan. Additional ultrasounds may be needed if there are complications or if the doctor wants to monitor the baby’s growth. Your healthcare provider will decide based on your specific needs.

Q7. How do I prepare for an ultrasound scan?

For early pregnancy scans, you may be asked to drink water and keep a full bladder for clearer images. Wear comfortable clothes and be ready to expose your abdomen or, for transvaginal scans, have an empty bladder. Bring any questions or concerns you have to discuss with the sonographer or doctor.
