Pregnancy scans are one of the most important tools used by doctors to check on the baby’s health. These scans provide visual confirmation of pregnancy, track development, and help detect any potential issues early. Understanding the different types of scans, when they are done, and what to expect can give you peace of mind throughout your pregnancy journey.
What is a Pregnancy Scan?
A pregnancy scan, also known as an ultrasound, is a medical test that uses sound waves to create images of your baby in the womb. Unlike a pregnancy test, which detects pregnancy through hormones in your urine, a scan gives a visual confirmation and detailed information about the baby’s development.
Pregnancy scans are performed for multiple reasons:
- To confirm pregnancy and detect the baby’s heartbeat
- To determine the number of embryos
- To locate the pregnancy inside the uterus
- To monitor growth and identify any complications
Ultrasound works by sending high-frequency sound waves into the abdomen or pelvis. These waves bounce off the baby and create images on a screen. Ultrasound is safe for both mother and baby as it does not use radiation.
When to Do the First Pregnancy Scan
The first pregnancy scan is usually done around six weeks of pregnancy. At this stage, the scan confirms whether the pregnancy is viable and helps detect the heartbeat.
- 4–5 weeks: At this very early stage, it may be too soon to see the heartbeat. The gestational sac may sometimes be visible, but confirmation of pregnancy is often better after six weeks.
- 6 weeks: This is the ideal time for the first scan. Doctors can confirm the pregnancy, check the number of embryos, and ensure the pregnancy is inside the uterus.
Early scans are important because they:
- Confirm that the pregnancy is progressing normally
- Detect multiple pregnancies, such as twins or triplets
- Identify potential complications, including ectopic pregnancy
Types of Pregnancy Scans and Their Purpose
Pregnancy scans are scheduled at different stages to check the baby’s growth, detect abnormalities, and ensure both mother and baby remain healthy. Here’s a detailed overview of the most common scans:
Early Pregnancy Scan (6–8 Weeks)
The early pregnancy scan is mainly performed to confirm that you are pregnant. It also helps your doctor see the exact location of the pregnancy and count the number of embryos.
What to expect:
- The scan may show a small gestational sac and a fetal pole, which is the first visible sign of the baby.
- The heartbeat may be visible at this stage.
- The procedure is usually quick, taking around 10–15 minutes.
This scan provides reassurance for expecting parents and allows the doctor to schedule future scans based on early findings.
Nuchal Translucency (NT) Scan (11–13 Weeks)
The NT scan is performed in the first trimester, usually between 11 and 13 weeks, and focuses on early detection of chromosomal abnormalities.
- It measures the thickness of the fluid at the back of the baby’s neck.
- Increased thickness can indicate a higher risk of conditions like Down syndrome or other chromosomal issues.
- This scan is often combined with blood tests to provide a more accurate assessment.
The NT scan is non-invasive and gives parents early insights into potential genetic risks.
Anomaly or TIFFA Scan (18–22 Weeks)
The anomaly scan, also called the TIFFA scan, is performed around 18–22 weeks. It is one of the most detailed scans and helps assess the baby’s growth and structural development.
- Doctors examine all major organs, including the heart, brain, kidneys, and spine.
- The position of the placenta and the amount of amniotic fluid are also checked.
- This scan is crucial for identifying structural abnormalities that might require monitoring or early intervention.
Parents receive detailed information about the baby’s development, giving them reassurance and time to plan if any issues are detected.
Growth Scan (28–32 Weeks)
The growth scan is performed in the third trimester to monitor the baby’s size and development.
- It measures the baby’s weight, size, and growth rate.
- Checks the position of the baby and placenta to ensure a safe delivery.
- Assesses amniotic fluid levels to ensure the baby has a healthy environment.
This scan is especially important for mothers who have had previous complications or are considered high-risk.
Doppler Scan (If Required)
A Doppler scan evaluates blood flow in the baby and placenta.
- It is recommended when there is concern about fetal growth, low amniotic fluid, or maternal conditions such as high blood pressure.
- Doppler scans check whether the baby is receiving enough oxygen and nutrients through the placenta.
This scan is typically performed as needed rather than routinely.
3D/4D Scans
3D and 4D scans provide parents with a clear, detailed view of the baby.
- 3D scans show static three-dimensional images.
- 4D scans create live motion images, allowing you to see the baby moving in real time.
- These scans are optional and mostly for bonding and keepsake purposes.
It is important to note that 3D and 4D scans do not replace medically necessary scans like NT or TIFFA scans.
How to Prepare for a Pregnancy Scan
Proper preparation ensures the scan is accurate and comfortable:
- Full Bladder: For early scans, a full bladder helps improve the clarity of the image.
- Clothing: Wear comfortable, loose clothing for easy access to the abdomen.
- Previous Reports: Bring any prior scan results for comparison.
- Diet: No special diet is needed unless advised by your doctor.
Arriving a few minutes early can help you feel relaxed and ready for the procedure.
Understanding Your Pregnancy Scan Report
Scan reports often include terms that may be unfamiliar. Here’s a simple guide to understanding them:
- Gestational Sac: The fluid-filled structure that surrounds the embryo in early pregnancy.
- Fetal Pole: The first visible sign of a developing baby.
- Crown-Rump Length (CRL): The measurement used to estimate gestational age.
- Amniotic Fluid: Fluid surrounding the baby, important for cushioning and development.
- Placenta Position: Indicates where the placenta is attached in the uterus.
Always consult your doctor if you have questions about your report. They can explain the findings and suggest any necessary follow-up tests.
Where to Get a Pregnancy Scan Near You
Choosing a certified diagnostic or women’s health center ensures accurate results and professional care:
- Look for facilities with experienced sonographers and certified equipment.
- Ensure the clinic is accredited and follows standard safety protocols.
- Ask about additional services like home sample collection for blood tests or early appointments for busy schedules.
A reliable center provides reassurance and proper guidance throughout your pregnancy journey.
Common Questions About Pregnancy Scans
How many scans are done during pregnancy?
Most pregnancies involve three main scans: the early pregnancy scan (6–8 weeks), NT scan (11–13 weeks), and anomaly or TIFFA scan (18–22 weeks). Additional scans such as growth scans, Doppler scans, or 3D/4D scans may be done based on medical advice.
What is the name of the scan for pregnancy?
Pregnancy scans are also called ultrasounds. Specific types include NT scan, anomaly/TIFFA scan, growth scan, Doppler scan, and optional 3D or 4D scans.
Is a scan for pregnancy safe?
Yes, pregnancy scans use sound waves, not radiation, making them safe for both the mother and the baby.
Can a scan detect pregnancy at 4 weeks?
At 4 weeks, it may be too early to detect the heartbeat. A gestational sac may sometimes be seen, but confirmation is usually more accurate around 6 weeks.
What is the cost of a pregnancy scan in the UAE or India?
Costs vary depending on the type of scan and facility. Basic scans are generally affordable, while advanced scans like 3D/4D or TIFFA scans may cost more.
Do I need a full bladder for the scan?
For early pregnancy scans, a full bladder helps produce clearer images. Later scans often do not require a full bladder.
How should I interpret my scan report?
Terms like gestational sac, fetal pole, and CRL indicate the stage and health of the pregnancy. Always consult your doctor for clarification.
