Understanding the Difference Between Antenatal Ultrasound and Fetomaternal Ultrasound

For many pregnant women, the terms Antenatal Ultrasound and Fetomaternal Ultrasound might sound similar. Both indeed use ultrasound technology to monitor the baby, but they have very different focuses and purposes. Understanding the difference is important so expectant mothers know when to undergo each type of examination.

Antenatal Ultrasound (Routine Check-Up)

Antenatal Ultrasound is the standard ultrasound routinely performed during pregnancy. Its purpose is to monitor the general condition of the pregnancy and ensure everything is progressing normally.

Main Focus:

Monitoring Fetal Growth: The doctor measures the size of the fetus to ensure development matches the gestational age.

Fetal Position and Heartbeat: This ultrasound also checks the position of the fetus in the womb and ensures the heartbeat is strong and regular.

Amniotic Fluid Volume: The doctor evaluates the amount of amniotic fluid, which is crucial for lung development and fetal movement.

Basic Screening: This includes checking the position of the placenta and estimating fetal weight.

This examination is usually performed by an Obstetrics and Gynecology (OBGYN) specialist as part of routine prenatal care.

Fetomaternal Ultrasound (Advanced Evaluation)

Unlike Antenatal Ultrasound, Fetomaternal Ultrasound is not a routine check-up. It is a more in-depth evaluation conducted at certain stages of pregnancy, especially recommended for high-risk pregnancies.

Main Focus:

Detailed Organ Examination: A fetomaternal subspecialist evaluates fetal organs (such as the heart, brain, spine, kidneys) in detail to detect congenital abnormalities.

Blood Flow (Doppler): Using Doppler technology, the doctor measures blood flow in the umbilical cord and fetal arteries, which is important for assessing whether the baby is receiving enough oxygen and nutrients—especially in cases like preeclampsia or fetal growth restriction.

Placenta and Umbilical Cord Conditions: This scan focuses on detecting issues such as placenta previa, placental abruption, or umbilical cord entanglement.

Chromosomal Risk Assessment: Fetomaternal ultrasound can help identify markers or signs of chromosomal abnormalities, such as Down syndrome.

This examination is conducted by a fetomaternal subspecialist with specific expertise and specialized equipment to diagnose more complex conditions.

While Antenatal Ultrasound is a routine check-up, Fetomaternal Ultrasound is a specialized scan aimed at identifying and managing high-risk conditions, ensuring the health of both mother and baby.

At National Hospital, you can undergo a Fetomaternal Ultrasound with an expert medical team. Don’t forget to schedule regular check-ups for both mother and baby’s health at National Hospital.
