Umbilical artery
Assess resistance in blood flow between the fetus and placenta when indicated.
Blood-flow assessment
Check blood flow to the baby.
Fetal Colour DopplerDoppler ultrasound examines blood-flow patterns in selected fetal and placental vessels when that information is relevant to growth or wellbeing.
Book a pregnancy scan
Doppler adds a different type of information to fetal measurements.
Practical steps for this examination.
Preparation and follow-up depend on the examination and what it shows.
- 01
Know why it was prescribed
The required vessels and measurements depend on the clinical concern.
- 02
Bring prior growth reports
Trend information can be important for interpretation.
- 03
Do not read one number alone
Doppler indices need gestational-age and clinical context.
- 04
Follow the obstetric plan
Abnormal findings may change surveillance or prompt further assessment.
01
Doppler adds a different type of information to fetal measurements.
A growth scan describes size. Doppler assesses selected blood-flow patterns. The two may be considered together when placental function or fetal wellbeing requires closer monitoring.
Medical ultrasound and Indian law
Maa Clinic does not determine or disclose fetal sex. This examination is performed for a medical purpose in accordance with the PC-PNDT Act.
What this examination is designed to review.
Other vessels
Additional fetal or uterine vessels may be assessed for a specific clinical reason.
Combine findings
Interpret waveforms alongside growth, fluid and maternal health.
Set the interval
Use the complete clinical picture to decide whether and when monitoring should be repeated.
Questions about fetal colour doppler
These answers are general. Individual advice depends on the clinical history and assessment.
Reception can help with appointment details
No. Growth measurements assess fetal size, while Doppler evaluates blood-flow patterns in selected vessels.
No. Colour represents the direction and relative characteristics of blood flow, not a direct oxygen reading.
Different vessels answer different clinical questions. The sonologist chooses them according to the referral and findings.
No. Management depends on gestational age, the specific vessel, severity, trend and the rest of the maternal and fetal assessment.
It may be repeated when ongoing surveillance is clinically useful. The interval should be individualised.
