Types of Pregnancy Scans in India: Your Complete Guide

Pregnancy is a journey filled with hope, curiosity, and sometimes, anxiety. One of the most reassuring parts of this journey is seeing your baby during an ultrasound during pregnancy.

Pregnancy scans are not just about seeing your baby move or wave on the screen. They are crucial for monitoring your baby’s growth, checking for abnormalities, and ensuring your pregnancy is progressing well.

If you are looking for a clear pregnancy scan schedule in India, this guide will help you understand the importance of pregnancy scans, what each scan checks, and how to prepare for them, trimester by trimester.

Pregnancy Scan Schedule: Trimester-Wise Overview

Here’s a trimester-wise pregnancy scans table for your easy reference:

Trimester	Recommended Scans	Timing	Purpose
First Trimester	Early Pregnancy Scan (Dating/Viability), NT Scan	6-9 weeks, 11-14 weeks	Confirm viability, detect pregnancy due date, detect multiple pregnancies, and check for chromosomal abnormalities
Second Trimester	Anomaly Scan (TIFFA Scan), Growth Scan	18-22 weeks, 28-32 weeks	Check structural abnormalities, monitor growth, and amniotic fluid levels
Third Trimester	Growth Scan, Doppler Scan	32-36 weeks	Monitor fetal growth, placental function, blood flow, and detect intrauterine growth restriction

Your Pregnancy Scan Schedule: What to Expect at Each Stage?

1. Early Pregnancy Scan (Dating Scan / Viability Scan)

Timing: 6-9 weeks

Purpose: Confirm pregnancy, check heartbeat, and date the pregnancy accurately.

What it checks?: Location of pregnancy (to rule out ectopic), number of fetuses, fetal heartbeat.

2. NT Scan (Nuchal Translucency Scan)

Timing: 11-14 weeks

Purpose: Screening for chromosomal abnormalities like Down syndrome.

What it checks?: Fluid at the back of the baby’s neck, nasal bone presence, and early anatomy check.

3. Anomaly Scan (TIFFA Scan)

Timing: 18-22 weeks

Purpose: Detailed anatomical assessment of the baby.

What it checks?: Baby’s organs, spine, limbs, brain, heart, and facial structures for abnormalities.

4. Growth Scan

Timing: 28-32 weeks, may repeat in the 3rd trimester if required.

Purpose: Assess fetal growth, amniotic fluid, and fetal movements.

What it checks?: Baby’s weight estimation, placenta position, and overall fetal well-being.

5. Doppler Scan

Timing: 32-36 weeks or earlier in high-risk cases.

Purpose: Evaluate blood flow to the baby and placenta, detect fetal distress.

What it checks?: Placental function, umbilical artery resistance, and fetal blood flow patterns.

How to Prepare for Each Pregnancy Scan?

Understanding how to prepare for a pregnancy scan helps reduce stress and ensures clear imaging.

• First Trimester Scans: A full bladder is often required. Drink 3-4 glasses of water an hour before your scan.
• Second Trimester Scans: Usually, a moderately full bladder is sufficient. Loose clothing helps for easy access during the scan.
• Third Trimester Scans: Typically, a full bladder is not necessary unless advised.

Pregnancy scan precautions:

• Avoid wearing heavy jewellery.
•  Carry previous scan reports for reference.
•  Eat something light unless fasting is advised.
• Arrive on time to avoid rushed scanning.

Preparing well can make your prenatal imaging experience more comfortable.

Specialized Scans & When They May Be Needed?

In high-risk pregnancy scans, extra monitoring may be required. This may include:

Targeted Level-II Scan: For detailed anomaly assessment if an abnormality is suspected.

Serial Growth Scans: For mothers with hypertension, diabetes, or a previous history of IUGR.

Doppler Studies: To monitor fetal well-being in cases of reduced fetal movements or abnormal growth patterns.

Fetal Echocardiography: If there is a risk of heart defects.

These extra scans during pregnancy ensure timely intervention if issues are detected, improving outcomes for mother and baby.

It is a prenatal imaging technique using sound waves to create images of your baby inside the womb, helping monitor development.

• How many ultrasound scans are there in pregnancy?

Typically, three to five scans are recommended, but it may vary based on medical needs.

• TIFFA scan is done in which week?

The TIFFA scan, or anomaly scan, is done between 18-22 weeks of pregnancy.

• Is it possible to find out the baby’s gender during an ultrasound in India?

No, revealing the baby’s gender during an ultrasound during pregnancy is illegal in India under the PCPNDT Act.

• What are the key scans done during pregnancy in India?

The key scans done during pregnancy in India include:

• Early Pregnancy Scan (6-9 weeks)
• NT Scan (11-14 weeks)
• Anomaly Scan (18-22 weeks)
•  Growth Scan (28-32 weeks)
• Doppler Scan (32-36 weeks if needed)

Are 3D/4D ultrasounds safe during pregnancy?

Yes, 3D/4D ultrasounds are safe during pregnancy when performed by trained professionals. However, they are not routinely necessary and are mostly used for detailed structural evaluation if required.

Are high-risk pregnancy scans different?

Yes, high-risk pregnancy scans may involve:

• More frequent monitoring
• Doppler studies
• Specialized fetal heart scans
•  Early growth assessments to ensure maternal and fetal health.
