Growth Scan & Fetal Doppler in Kollam – Third Trimester Monitoring

Essential third-trimester assessments to ensure your baby is growing well and receiving adequate oxygen and nutrients through the placenta.

What is a Growth Scan?

A growth scan is a serial ultrasound performed in the third trimester to monitor your baby's development. By measuring four parameters — the baby's head (BPD, HC), abdomen (AC), and femur (FL) — we calculate estimated fetal weight and plot it on growth charts to ensure appropriate development.

Recommended Growth Scan Timeline

28 weeks
First third trimester growth scan — establishes baseline weight and Doppler indices.
32 weeks
Second growth scan — critical for detecting early IUGR and placental dysfunction.
36–38 weeks
Final pre-delivery scan — checks position, amniotic fluid, and estimated weight.
Any gestation
Performed immediately if: reduced fetal movements, hypertension, diabetes, or previous IUGR concerns.

What is Fetal Doppler?

Fetal Doppler measures blood flow velocity in specific fetal and placental vessels — the placental lifeline. It is the most powerful tool available to detect placental dysfunction (IUGR) early, often weeks before it becomes clinically apparent.

Umbilical Artery Doppler

Measures placental resistance. Elevated resistance or absent end-diastolic flow indicates placental dysfunction.

Middle Cerebral Artery (MCA)

Detects "brain sparing" — the fetus redirecting blood flow to protect the brain in IUGR.

Uterine Artery Doppler

Assesses pre-eclampsia and IUGR risk. Used from 20–24 weeks in high-risk pregnancies.

Ductus Venosus Doppler

Evaluates fetal cardiac function. Abnormal waveform signals imminent decompensation.

What Can Be Detected?

Growth scans combined with Doppler studies detect IUGR (Intrauterine Growth Restriction), placental insufficiency, fetal anaemia (elevated MCA peak systolic velocity), and fetal distress. These findings guide the obstetrician in making critical decisions — including the optimal timing of delivery — to ensure the best possible outcome for your baby.
