| Trimester | Week | Scan Name | Purpose |
| 1st Trimester | 6 to 8 weeks | Early Pregnancy Scan | To confirm pregnancy, check the baby’s position, heartbeat, and estimate gestational age. |
| 11 to 13 weeks | NT Scan (Nuchal Translucency Scan) | To check for chromosomal abnormalities, measure nuchal translucency, and assess early fetal anatomy. | |
| 2nd Trimester | 18 to 20 weeks | Anomaly Scan / TIFFA Scan | To examine the baby’s anatomy and detect structural defects in the baby and placenta. This is the most important pregnancy scan. |
| 24 to 26 weeks | Cardiac Scan / Fetal Echocardiography | To evaluate the structural and functional integrity of the fetal heart. | |
| 3rd Trimester | 28 to 32 weeks | Pregnancy Welfare & Growth Scan | To monitor the baby’s growth, position, and amount of amniotic fluid (liquor). |
| 28 to 32 weeks (Optional) | Obstetric Doppler Scan | To measure blood flow through the umbilical cord and internal organs, assessing placental function and fetal well-being. | |
| 36 to 40 weeks | Growth Scan / Final Scan | To check the baby’s position, growth, fluid levels, and blood flow before delivery. |
Yes, pregnancy ultrasound scans are absolutely safe for pregnant women as they use sound waves instead of radiation. These scans are performed professionally by sonographers, radiologists, or gynaecologists. They are done at different stages of pregnancy and provide detailed information about the health and well-being of both the unborn baby and the mother.
All pregnancy ultrasound scans are not necessarily mandatory but are highly recommended. Your gynaecologist may prescribe scans such as the early pregnancy scan, dating scan, or growth scan, depending on your condition. It is best to follow her advice, as she is an experienced professional who will guide you to make your pregnancy journey smoother and safer. Proper diagnosis through these ultrasound scans helps in identifying potential risks early and developing a suitable care plan.
An anomaly scan, also known as a TIFFA scan (Targeted Imaging for Fetal Anomalies), is one of the most important pregnancy scans performed during the second trimester. It is often referred to as the 20-week ultrasound or Level II scan. This scan is usually done between 18 to 22 weeks of pregnancy but can be performed up to 28 weeks of gestational age. The sonographer examines the baby’s anatomy, observing the internal organs and identifying any structural defects or soft markers from head to toe. The scan can detect major congenital deformities such as Down Syndrome (50%), Cleft Lip (75%), Anencephaly, Gastroschisis (98%), Edwards Syndrome (Trisomy 18) (95%), and congenital heart disease (50%).
Yes, there are some limitations. While most anomalies can be identified, the scan is not 100% accurate. Some defects may develop later in pregnancy and cannot be detected during the 18–20-week window. Factors such as obesity, the baby’s position, or multiple pregnancies (twins/triplets) may make it difficult to visualise certain anomalies. Conditions like soft tissue fusion, absence of anal or auditory openings, or cleft palate (beyond the lip) may not be detected.
An anomaly scan at 18–20 weeks cannot guarantee a completely healthy baby at 40 weeks, as many developments occur later. However, in most cases, major anomalies are detected during this scan when performed by experienced professionals using advanced ultrasound machines.
Note: Even if your scan is normal, there remains a small chance of undetected issues. Some heart defects (like coarctation of the aorta, VSDs, ASDs) and conditions such as biliary atresia, bowel obstructions, CDH, or ear/orbital anomalies may appear later in pregnancy. Still, most babies are born healthy and normal after a clear anomaly scan.
A healthy and normal pregnancy typically requires only the standard ultrasound scans mentioned in the regular schedule. However, additional scans may be advised in certain cases, such as multiple pregnancies (twins or triplets), fetal growth restrictions, or high-risk pregnancies. Your gynaecologist may recommend more frequent ultrasounds to closely monitor the baby’s health and development.
