Seeing your baby for the first time on that ultrasound screen is truly magical. That tiny heartbeat flickering, those little movements, these moments make pregnancy feel real and fill your heart with joy.
But sonography in pregnancy is more than just an emotional experience. It’s an important medical test that helps doctors monitor your baby’s growth and keep both of you healthy throughout the nine months.
If you’re pregnant and wondering when to get your scans done, what happens during the test, or whether it’s safe, this guide will answer all your questions in simple, easy-to-understand language.
What is Sonography in Pregnancy?
Sonography, also called ultrasound or pregnancy scan, uses sound waves to create images of your baby inside the womb. It’s completely painless and doesn’t use any radiation like X-rays do.
Think of it like a camera that can see through your belly to show how your baby is growing. The doctor or technician moves a small device called a probe over your belly, and you can see your baby moving on a screen.
Why is it Important?
Pregnancy sonography helps doctors:
- Confirm your pregnancy and calculate your due date
- Check your baby’s heartbeat and growth
- See if your baby is developing properly
- Monitor the placenta and amniotic fluid
- Detect any health concerns early
- Determine your baby’s position before delivery
When Should You Get Sonography Done?
Sonography is done at specific stages of pregnancy to check the baby’s growth and your overall health.
1. Early Pregnancy Scan (6–8 weeks)
This first scan confirms the pregnancy, checks the baby’s heartbeat, and ensures the pregnancy is inside the uterus (not ectopic). It also helps estimate the due date.
2. NT Scan (Nuchal Translucency) – 11 to 14 weeks
The NT scan helps assess the baby’s risk for certain chromosomal conditions.
It is not mandatory, but is advised by your gynecologist based on your age, medical history, and pregnancy condition.
3. Anomaly Scan (18–22 weeks)
This is one of the most detailed and important scans. It checks the baby’s organs, limbs, brain, spine, heart, and placenta.
⚠️ Important: The baby’s gender is not revealed in this scan — or any scan — as it is illegal under Indian law (PCPNDT Act). The purpose of the anomaly scan is purely medical.
4. Fetal 2D Echo (23–24 weeks)
This scan checks your baby’s heart in detail and helps detect any early signs of abnormalities or heart concerns.
5. Growth Scan (32–36 weeks)
A growth scan checks the baby’s size, position, and fluid levels later in pregnancy.
This scan is not mandatory and is usually advised only if your gynecologist feels it’s necessary, such as in cases of high blood pressure, diabetes, or when there’s concern about the baby’s growth or movement.
What to Expect During a Sonography Scan
Knowing what happens during the scan can make the experience more comfortable.
Before the Scan
- You may be asked to drink water and keep your bladder full for early pregnancy scans.
- Wear comfortable clothes and carry your doctor’s referral.
- A clear gel will be applied to your abdomen to help the machine capture images.
During the Scan
- A small device called a transducer is gently moved over your belly.
- The sound waves create images of your baby on a monitor.
- The process is painless and usually takes 15–30 minutes.
- In early pregnancy, your doctor may perform a transvaginal scan for clearer results.
After the Scan
- You’ll receive a printed report and sometimes images of your baby.
- Your doctor will discuss the findings and advise if any follow-up is needed.
Types of Scans Available
- 2D Ultrasound: Standard and most commonly used for medical evaluation.
- 3D/4D Ultrasound: Provides more detailed or moving images, usually optional.
Understanding Your Report
Your sonography report includes several measurements that show how your baby is growing:
- CRL (Crown-Rump Length): Your baby’s length in early pregnancy
- BPD: Head measurement
- FL: Thigh bone length
- EFW: Your baby’s estimated weight
- AFI: Amount of fluid around your baby
- FHR: Your baby’s heartbeat (normal is 120-160 beats per minute)
- AC: Abdominal Circumference
Don’t worry if the numbers look confusing! Your doctor will explain what they mean and whether everything is normal.
Is Sonography Safe?
Yes, sonography is completely safe for both you and your baby. It uses sound waves, not radiation, and has been used safely worldwide for over 40 years. The World Health Organization and Indian medical associations recommend it as a safe way to monitor pregnancy.
Frequently Asked Questions (FAQs)
Q1. How many scans do I need during pregnancy?
Typically, at least 3 scans are recommended. Your gynecologist may advise additional scans based on your health condition and pregnancy progress.
Q2. Why can’t doctors tell me my baby’s gender?
Gender determination and disclosure are illegal in India under the PNDT Act. This law protects against gender discrimination. Sonography is meant only for monitoring your baby’s health.
Q3. What if something abnormal shows up?
Don’t panic. Many findings are minor and resolve on their own. Your doctor will explain everything clearly and guide you on the next steps if needed.
Q4. How much does pregnancy sonography cost in India?
Typically between ₹700 and ₹2,500 for 2D scans, and ₹3,000–₹6,000 for 3D/4D scans in private centres.
