Scans for each trimester
Below are various scans recommended for different trimesters. Please consult your doctor for personalised guidance on selecting the most appropriate scan for your specific condition.
Fetal Assessment Unit
Thomson's Fetal Assessment Unit (FAU) is dedicated to ensuring the well-being of both expectant mothers and their babies. As the first private hospital unit of its kind in Singapore, our FAU is staffed by a Consultant Maternal Fetal Medicine Specialist and a team of experienced sonographers who are committed to providing comprehensive obstetric ultrasound and prenatal diagnostic services.
Our Fetal Assessment Services include:
- First Trimester Pre-Eclampsia Screening
- One-stop Clinic for Assessment of Risk for Fetal Anomalies (OSCAR)
- Fetal Anomaly Scan
- 3D/4D Ultrasound Scans
- Additional Services
Please see below for more information.
First Trimester Pre-Eclampsia Screening
This is a non-invasive screening test performed during the first trimester to assess the risk of developing Pre-eclampsia.
- Pre-eclampsia, a serious pregnancy complication, affects 2 in 100 pregnancies.
- Our screening includes a specific blood test for PlGF, blood pressure measurement, and ultrasound examination.
- Early detection and treatment can help prevent pre-eclampsia.

One-stop Clinic for Assessment of Risk for Fetal Anomalies (OSCAR)
This examination includes a screening scan for early assessment of fetal anatomy (organ development) and the evaluation of specific ultrasound markers, including Nuchal Translucency (NT) and nasal bone.
- Offered in the first trimester to screen for fetal anomalies, particularly Down Syndrome (Trisomy 21).
- Provides earlier reassurance for those with a normal result.
- Helps in deciding whether invasive testing (such as CVS or Amniocentesis) is necessary.
For detailed information on OSCAR, please download our e-brochure.
Fetal Anomaly Scan
This is a detailed 2D ultrasound scan at 20 to 22 weeks to assess fetal physical development and growth.
- Screens for structural deformities in the brain, heart, spine, and more.
- Gender determination available upon request.
- Evaluates the location of the placenta and amniotic fluid levels.
3D/4D Ultrasound Scans
Experience the joy of seeing your unborn child through 3D/4D ultrasound scans. A 3D ultrasound scan provides a photographic image of the baby while the 4D ultrasound scan provides a moving image of the baby.
- Performed by experienced sonographers in a relaxed environment.
- A 2D scan is also included to assess growth and exclude anomalies.
- A referral letter from your doctor is required for appointment booking
Additional Services
In addition to the standard pregnancy scans, we offer a comprehensive range of supplementary services to provide you with the utmost care and support.
- Ultrasound imaging for risk assessment of chromosomal abnormalities in the first trimester (Nuchal Translucency Measurement)
- Second-trimester Fetal Anomaly (FA) Scanning
- Cervical Length Measurements for prediction of pre-term labour
- Uterine Doppler assessment for prediction of pre-eclampsia and poor fetal growth
- Ultrasound monitoring using Doppler colour flow imaging, as well as the biophysical profile
- Amniocentesis
- Thalassaemia Studies
- Chorionic Villus Sampling
- Cordocentesis/Fetal Blood Sampling
- Multiple pregnancy (twins/triplets/quadruplets) fetal assessment
