Fetal Medicine Scans — From Dating to Doppler

Our approach to fetal scanning

All scans at Balaji Horizon follow ISUOG (International Society of Ultrasound in Obstetrics and Gynecology) protocols. Reporting is structured — patients receive a written report covering every required parameter, not just summary impressions. Where a scan raises concern, the next step (additional imaging, MRI, genetic counselling, referral) is explained in the same conversation. We do not rush the consultation that follows a scan with findings.

First-trimester scans

The dating + viability scan establishes gestational age, confirms cardiac activity, and identifies multiple pregnancies. The NT (nuchal translucency) scan between 11–14 weeks is part of first-trimester combined screening for chromosomal conditions, performed to FMF (Fetal Medicine Foundation) standards.

Second-trimester scans

The anomaly scan around 18–22 weeks is the detailed fetal anatomic survey. ISUOG protocols specify every structure to be examined. Soft markers, when present, are interpreted in context — most are normal variants, but the conversation about their significance is part of the scan visit.

Third-trimester and late scans

Growth scans, doppler assessments, placental and amniotic fluid scans, cervical length scans where indicated — each has specific clinical questions. The 3D/4D wellbeing scan is offered as a parent-experience scan separate from diagnostic monitoring.

Scan types covered

Guidelines we follow

• ISUOG practice guidelines on fetal ultrasonography
• FMF certification standards for first-trimester screening
• RCOG green-top guidelines on fetal monitoring
• FIGO statements on prenatal imaging

Where this fits

Scans support screening, identify conditions that need attention, and inform procedures when indicated.
