Pregnancy Scan List: Important Pregnancy Scans in India

Prenatal scanning serves a critical purpose in checking the health of the growing baby as well as the health of the mother. Most expecting parents are not aware of the list of scans during pregnancy that are needed, and their timing.

In India, a sequence of precisely planned scans identifies possible complications early on, follows fetal growth, and gives parents reassurance. This article gives a complete list of scans during pregnancy in India, a week-by-week scan plan, and discusses why each scan is necessary.

List of Scans During Pregnancy in India

Scans during pregnancy are normally performed in three trimesters. Every scan serves a purpose, ranging from pregnancy confirmation to fetal development monitoring and detection of abnormalities.

Early Pregnancy Scans (6–11 Weeks)

Dating Scan

Confirms pregnancy and approximates the due date.

Checks for more than one pregnancy (twins or more).

Aids in the identification of any complications during early pregnancy, including ectopic pregnancy.

‍

2. NT Scan (Nuchal Translucency Scan): 11 weeks to 13 weeks + 6 days

Checks for chromosomal defects like Down syndrome.

Assess the fluid at the nape of the baby's neck.

Usually done alongside a blood test to increase accuracy.

Second Trimester Scans (18–22 Weeks)

Anomaly Scan

Detailed fetal anatomy scan to identify structural defects.

Inspects organs, including the brain, heart, kidneys, and spine.

Assists in identifying the location of the placenta and the level of amniotic fluid.

‍

Fetal Echo (Fetal Echocardiography)

Assesses fetal heart structure and function.

Recommended for families with a history of heart abnormalities or for those with abnormal initial scans.

Third Trimester Scans (28–32 Weeks)

Growth Scan

Tracks the baby's weight and growth.

Verifies the level of amniotic fluid and the functioning of the placenta.

Aids in the detection of growth restrictions or other abnormalities.

Doppler Scan

Examines the flow of blood in the umbilical cord, fetal vessels, and placenta.

Ensures the baby is receiving proper oxygen and nutrients.

‍

3D/4D Scans (Optional)

Gives clear images of the baby's face and body.

Used for evaluation and bonding, it sometimes identifies physical abnormalities.

Week-by-Week Scan Schedule

Following is a list of scans during pregnancy week-by-week breakdown, providing a clear idea of what to expect:

First Trimester (6–12 Weeks)

Dating Scan: 6–8 weeks

NT Scan: 11–14 weeks

‍

Second Trimester (13–27 Weeks)

Anomaly Scan: 18–22 weeks

Fetal Echo (if indicated): 20–24 weeks

‍

Third Trimester (28–40 Weeks)

Growth Scan: 28–32 weeks

Doppler Scan: 28–36 weeks

3D/4D Scans (optional): 28–36 weeks

Why Each Scan is Performed

Understanding the purpose of each scan can help expectant parents feel more relaxed and informed:

Dating scan: This test confirms pregnancy, determines the gestational age, and checks for multiple pregnancies.

NT scan: Screens for chromosomal abnormalities; an early diagnosis gives you early counselling and options.

Anomaly scan: Identifies structural abnormalities, confirms organs are developing appropriately, and informs of any intervention if required.

Fetal echo: Screens heart health, allowing you to plan for congenital heart disease.

Growth Scan: Monitors growth and amniotic fluid levels, detects growth restrictions or macrosomia.

Doppler Scan: Verifies adequate circulation of blood and oxygen to the fetus.

3D/4D Scan: Provides advanced imagery for evaluation and family bonding purposes; also aids in visualising some structural malformations. Regular scanning ensures timely detection of complications, enables planning by healthcare professionals for intervention if required, and gives parents reassurance.

Are All Pregnancy Scans Necessary?

Not every woman needs every pregnancy scan. Some scans are part of routine checkups and need to be done. Some are done for a specific reason. Your gynaecologist will plan your scan schedule based on how your pregnancy is progressing and how your body is handling it. Here are a few things that will be part of your doctor’s decision when deciding on your scans:

Mom-to-be’s health - if you have any conditions like diabetes, high blood pressure, thyroid or low BMI, you may need close monitoring and a few additional scans to do so.

Pregnancy history - if you had a miscarriage, a preterm delivery ot any complications in an earlier pregnancy, additional scans may be needed.

Other pregnancy risks - if you are having 2 or more babies, are at an older maternal age or any genetic conditions running in the family, the scan plan may be different.

Any foetal growth parameters or ultrasound findings - if the scan shows that the amniotic fluid, baby’s growth, or the placenta is abnormal, the doctor may request repeat scans at certain intervals.

So if a friend had six scans and you have been advised three, it does not mean anything is wrong. Fewer scans usually means your pregnancy is progressing as expected.

What to Expect Before a Pregnancy Ultrasound

A pregnancy ultrasound is simple and painless. Here is what you need to know before you go for it:

Do You Need to Fast Before a Pregnancy Ultrasound?

No, fasting is not required. You can eat and drink as you normally would on the day of your appointment. Fasting is usually only required for scans of the upper abdomen, such as the liver or gallbladder, which is different from a routine pregnancy scan. Preparation can still vary depending on the type of scan and the centre you visit, so always follow the instructions given to you when you book your appointment.

Do You Need a Full Bladder for a Pregnancy Scan?

Sometimes, yes. For certain early pregnancy scans done through the abdomen, usually in the first trimester, you may be asked to come with a full bladder. A full bladder gently pushes the intestines out of the way and gives a clearer view of the uterus. In such cases, you will be told how much water to drink and when.

For scans done later in pregnancy, a full bladder is generally not needed, as the growing uterus is already easy to see. A full bladder is also not required for a transvaginal scan. If holding your bladder becomes uncomfortable at any point, do tell the sonographer.

What Should You Wear for a Pregnancy Ultrasound?

Always wear something comfortable and loose for easy access to your abdomen. A loose kurta, a two-piece salwar kameez, or a top and pants that can be lifted or lowered easily work well. A one-piece dress or a tightly draped saree may need to be changed before the scan. Avoid heavy jewellery around your waist, and carry a stole or dupatta if you would like extra cover.

How Long Does a Pregnancy Ultrasound Take?

Most pregnancy ultrasounds take between 15-45 minutes. A quick dating scan or a growth scan may be over in 15-20 minutes, while a detailed anomaly scan takes longer because every organ and body part of the baby has to be checked carefully.

The scan can also take more time if your baby is lying in an awkward position. You may be asked to walk around for a few minutes or shift on your side so the baby moves. This is completely normal and is not a sign of any problem.

What Should You Bring to Your Ultrasound Appointment?

Carrying the right papers saves time and helps your doctor read the new scan in context. Your previous scan reports, any relevant medical records, your doctor's prescription, a list of medicines you are currently taking along with your ID and insurance details.
