Third Trimester Scans in Nagpur
Third trimester scans help monitor fetal growth, amniotic fluid, placental function, Doppler blood flow, fetal wellbeing and presentation. At Mayflower Fetal Medicine & High-Risk Pregnancy Centre, Nagpur, these scans are planned carefully for routine and high-risk pregnancies.
Why third trimester scans matter
```
The final months need growth, blood flow and wellbeing surveillance
The third trimester is when many pregnancies need careful monitoring for growth restriction, excess or reduced fluid, placental insufficiency, diabetes-related large baby, hypertension, twin pregnancy and delivery planning.
Doppler blood flow
Assesses fetal and maternal circulation, especially in IUGR, hypertension, pre-eclampsia and twin pregnancy.
Delivery planning support
Checks presentation, fluid, placenta and wellbeing parameters when your obstetrician is planning follow-up or delivery timing.
Scan timeline
Which third trimester scan do you need?
The right scan depends on pregnancy weeks, previous growth chart, maternal health, fetal movements, Doppler findings and your obstetrician’s referral reason.
28–32
weeks
Growth / Wellbeing Scan
Measures fetal head, abdomen, femur length, estimated fetal weight, amniotic fluid, placenta and general fetal wellbeing. It helps identify babies who are small, large or need closer surveillance.
28+
weeks
Colour Doppler Scan
Assesses umbilical artery, MCA, uterine artery and other Doppler vessels when indicated. Doppler is especially useful in IUGR, hypertension, pre-eclampsia, twins and fetal anaemia.
32–38
weeks
High-Risk Pregnancy Scan
Used when the pregnancy needs closer fetal surveillance due to diabetes, hypertension, IVF, twins, previous pregnancy complications, reduced growth, abnormal fluid or maternal medical conditions.
When
advised
Biophysical Profile / BPP
BPP may be advised when fetal wellbeing needs a more structured assessment. It evaluates parameters such as fetal movement, tone, breathing movements, amniotic fluid and sometimes NST correlation.
36+
weeks
Presentation / Late Pregnancy Scan
Checks whether the baby is cephalic, breech or transverse, along with fluid, placenta and other details that may help delivery planning when your obstetrician requests it.
Comparison table
Third trimester scans at a glance
| Scan type | What is assessed | When it is useful | Related concern |
|---|---|---|---|
| Growth / Wellbeing Scan | BPD, HC, AC, FL, estimated fetal weight, fluid, placenta and wellbeing markers. | Routine third trimester monitoring or when growth trend needs reassessment. | Small baby, large baby, diabetes, previous IUGR, IVF pregnancy. |
| Colour Doppler Scan | Umbilical artery, MCA, uterine artery and other vessels when clinically indicated. | When placental function, fetal oxygenation or blood flow pattern needs assessment. | IUGR, hypertension, pre-eclampsia, twins, fetal anaemia. |
| High-Risk Pregnancy Scan | Growth, Doppler, amniotic fluid, placenta and tailored monitoring based on risk factor. | When pregnancy needs closer surveillance beyond routine antenatal care. | Diabetes, hypertension, twins, previous loss, maternal illness. |
| BPP / Fetal Wellbeing Assessment | Fetal breathing, movement, tone, amniotic fluid and NST correlation when advised. | When structured fetal wellbeing assessment is requested by the treating doctor. | Reduced movements concern, post-date pregnancy, high-risk surveillance. |
| Presentation Scan | Fetal lie and presentation, fluid, placenta and basic wellbeing details. | Usually late pregnancy when delivery planning requires confirmation of baby’s position. | Breech, transverse lie, uncertain presentation, delivery planning. |
Important:
A third trimester scan does not replace regular antenatal visits. Ultrasound findings must be interpreted along with blood pressure, symptoms, fetal movements, lab reports and your obstetrician’s clinical plan.
Why Mayflower for third trimester monitoring?
Specialist growth and Doppler interpretation by Dr. Kunda Shahane
Dr. Kunda Shahane, MBBS, MS (Obs & Gynae), FIFM, FMF (London), is Central India’s first dedicated fetal medicine specialist, with nearly two decades of experience and 20,000+ fetuses evaluated.
In the third trimester, small differences in growth trend, Doppler pattern, amniotic fluid or fetal wellbeing may change follow-up frequency. At Mayflower Clinic, the scan is interpreted in context — not as an isolated number.

When closer follow-up may be advised
Some pregnancies need serial third trimester surveillance
Your obstetrician or fetal medicine specialist may advise repeat scans every few weeks depending on your risk profile and previous findings.
IUGR / small baby
Serial growth and Doppler help decide whether the baby is stable, needs closer monitoring or needs delivery planning.
Hypertension or pre-eclampsia
Doppler and growth surveillance can help assess placental function in pregnancies affected by high blood pressure.
Diabetes in pregnancy
Growth scan helps monitor whether the baby is growing larger than expected and whether fluid is increased.
Twin pregnancy
Twin pregnancies need serial growth, fluid and Doppler follow-up, especially monochorionic twins.
Fluid abnormality
Oligohydramnios or polyhydramnios may need repeat fluid assessment, Doppler and clinical correlation.
Reduced movements concern
When advised by the treating doctor, fetal wellbeing assessment and BPP may be part of the evaluation pathway.
How to prepare
What to bring for your third trimester scan
Bringing previous reports helps Dr. Kunda’s team compare growth trend and interpret Doppler in the correct clinical context.
Previous scan reports
Carry earlier anomaly scan, growth scans, Doppler reports, fetal echo reports and any high-risk pregnancy notes.
Maternal health reports
Bring BP records, diabetes reports, thyroid reports, Hb, urine reports or other tests if your obstetrician has advised them.
Referral question
Tell the clinic whether the scan is for growth, Doppler, BPP, fluid, presentation, twins or high-risk pregnancy surveillance.
Frequently asked questions
Third Trimester Scan FAQs
When should I do a third trimester growth scan?
Growth scans are commonly advised around 28, 32, 34, 36 or 38 weeks depending on pregnancy risk, previous growth pattern and your obstetrician’s recommendation.
Is Doppler needed with every growth scan?
Not always. Doppler is added when blood flow and placental function need assessment, especially in IUGR, hypertension, pre-eclampsia, twins, fetal anaemia or other high-risk situations.
What does a growth scan measure?
It usually measures fetal head, abdomen and femur length to estimate fetal weight. It also assesses amniotic fluid, placenta and other wellbeing details.
What is BPP?
Biophysical Profile is a structured fetal wellbeing assessment. It may include fetal breathing movements, fetal movements, tone, amniotic fluid and NST correlation when advised.
Can a third trimester scan decide delivery date?
The scan gives important information, but delivery timing is decided by your treating obstetrician after considering scan findings, Doppler, symptoms, maternal health and overall pregnancy condition.
Can fetal sex be disclosed during third trimester scans?
No. Mayflower Fetal Medicine & High-Risk Pregnancy Centre strictly follows the PCPNDT Act. Determination and disclosure of fetal sex is prohibited by law and is not performed.
