Specialized prenatal ultrasound Fetal anomaly screening

Prenatal ultrasound and anomaly screening are steps in assessing fetal morphology at important milestones of pregnancy. The goal is to detect structural abnormalities early, so that appropriate monitoring and counseling can be provided to the family.

Why is anomaly screening ultrasound needed?

Most pregnancies progress normally, but some abnormalities can only be recognized through ultrasound imaging. Screening at the right milestones helps the doctor assess fetal development, detect anomalies early and coordinate with relevant specialties when necessary.

Key screening milestones

• Weeks 11–13: nuchal translucency measurement, preliminary assessment of fetal morphology and some early anomalies.
• Weeks 18–22: detailed assessment of fetal morphology, heart, brain, spine, limbs and internal organs.
• Third trimester: monitoring of growth, placenta, amniotic fluid and screening for some late abnormalities.

Prenatal ultrasound at Phuc Khang

Every ultrasound is performed and interpreted directly by Dr. Truong Xuan Luc, MSc. The doctor clearly explains each image, helping parents correctly understand the condition of the fetus and avoid excessive worry based on incomplete information.

Preparation before the ultrasound

You do not need to fast and should urinate before the ultrasound. At some milestones, the doctor may schedule a repeat examination if the fetal position is not favorable for observation.

Notes

Screening ultrasound results do not replace a definitive diagnosis in all cases. When a suspicious abnormality is detected, the doctor will advise on the next steps, such as additional tests or specialist consultation.
