Pregnancy Scans Explained: Which Scan, When & Why in Amravati

Medically reviewed by Dr. Darshana Ajmera — MBBS (Nair, Mumbai), MS ObGyn (Honors), Obstetrician, Gynecologist & Fetal Medicine Specialist, Shubham Hi-Tech Hospital and Test Tube Baby Centre, Amravati.

During a healthy pregnancy you will usually have a few key ultrasound scans: a dating scan early on, an NT scan at around 11–13 weeks, a detailed anomaly scan at around 18–22 weeks, and growth scans later in pregnancy. Each scan checks something specific and is timed for a reason, so understanding them helps you feel prepared rather than anxious.

Pregnancy scans are one of the most reassuring parts of antenatal care, but the names and timings can be confusing. Here is a clear guide for expecting mothers in Amravati.

Why Pregnancy Scans Matter

Ultrasound scans let your doctor confirm that the pregnancy is progressing well, check the baby's growth and development, and pick up any concerns early — when there is the most time to plan and act. They also give you precious moments to see your baby. Scans are a routine, valuable part of safe maternity care, not a sign that something is wrong.

The Key Scans, in Order

1. The Dating (or Early) Scan — around 6–9 weeks

This first scan confirms the pregnancy is in the right place, checks the baby's heartbeat, and accurately dates the pregnancy to give you an expected delivery date. It also tells you whether you are expecting more than one baby.

2. The NT Scan — around 11–13 weeks

The nuchal translucency (NT) scan measures a small area at the back of the baby's neck and, combined with a blood test, helps assess the chance of certain chromosomal conditions such as Down syndrome. It is an important screening milestone in the first trimester.

3. The Anomaly Scan — around 18–22 weeks

This is the most detailed scan of pregnancy. The anomaly scan (also called the level 2 or TIFFA scan) carefully examines the baby's brain, heart, spine, face, kidneys, limbs and other organs to check that they are developing normally. It also looks at the position of the placenta and the level of amniotic fluid. You can read more about this on our fetal medicine page.

4. Growth and Doppler Scans — third trimester

Later in pregnancy, growth scans check that the baby is gaining weight well, and Doppler studies assess blood flow through the placenta and cord. These are especially important in high-risk pregnancies or if there is any concern about the baby's growth.

Are Pregnancy Scans Safe?

Yes. Ultrasound uses sound waves, not radiation, and has been used safely in pregnancy for decades. The scans recommended in routine antenatal care are considered safe for both mother and baby. Your doctor will advise the right number and timing for your particular pregnancy. You can see our imaging services on our ultrasound & imaging page.

What to Expect During a Scan

Most scans are done over the abdomen with a little gel; early scans are sometimes done internally for a clearer view. They are painless and usually take 15–30 minutes, with the detailed anomaly scan taking longer. For mothers travelling from across Amravati and Vidarbha — Akola, Yavatmal, Achalpur and nearby towns — it helps to book the anomaly scan in good time, as it must be done within a specific window.

Frequently Asked Questions

How many scans are needed in pregnancy?
A typical healthy pregnancy involves around three to four key scans, though your doctor may advise more if you have a high-risk pregnancy or any specific concern.

Which is the most important pregnancy scan?
The anomaly scan at 18–22 weeks is the most detailed, as it checks the baby's organs and development. The NT scan and growth scans are also important milestones.

Are ultrasound scans safe for my baby?
Yes. Ultrasound uses sound waves rather than radiation and has a long record of safe use in pregnancy when performed as part of routine care.

Can a scan tell me my baby's gender?
In India, by law, clinics cannot reveal the baby's sex, as prenatal sex determination is prohibited. Scans are used only to assess health and development.
