Early Pregnancy Scan

First Trimester Aneuploidy Screening

• between 11 weeks - 14 weeks

• risk assessment for trisomies - T21, T18, T13

• risk assessment for pre-eclampsia

• cervical length assessment

• early anatomical survey for structural anomalies

• optional biochemistry or cfDNA testing

Second Trimester Anomaly Screening

• suggested between 18 weeks - 24 weeks

• comprehensive detailed anatomical survey

• risk assessment for trisomy 21

• risk assessment for pre-eclampsia  

• cervical length assessment

• foetal cardiac evaluation - echocardiography

• foetal neurological evaluation - neurosonogram

• 3D / 4D / 5D foetal evaluation

Third Trimester Growth & Doppler

• suggested between 30 weeks - 34 weeks

• assessment for foetal growth

• 3D / 4D / 5D foetal evaluation

• study of foetal blood-flow using color Doppler

• evaluation for late-appearing anomalies

Multiple pregnancy (twins, triplets etc.)

• specialized assessment for multiple pregnancies

• monitoring for twin-specific complications

• TTTS, sFGR, TAPS, TRAP, single foetal demise

• counseling for foetal therapy

Foetal Invasive Testing
