What Is a 3D/4D Obstetric Scan?

A 3D/4D obstetric scan is a pregnancy ultrasound examination that can create three-dimensional images of the fetus, with 4D ultrasound adding the element of real-time movement.

A standard obstetric ultrasound generally produces two-dimensional images. Three-dimensional ultrasound processes ultrasound data to create a three-dimensional representation, while four-dimensional ultrasound allows those 3D images to be viewed with movement over time.

Depending on the examination and clinical purpose, obstetric ultrasound may provide information about:

• Fetal development
• Fetal growth
• Fetal position
• Fetal movement
• Fetal heart activity
• Placental location
• Amniotic fluid
• Number of fetuses
• Selected fetal anatomical structures

The exact information obtained depends on the stage of pregnancy, fetal position, examination type and clinical indication.

Why Is an Obstetric Ultrasound Recommended During Pregnancy?

An obstetric ultrasound may be recommended to monitor pregnancy and assess the fetus and pregnancy-related structures at different stages of pregnancy.

Depending on the examination, ultrasound may help healthcare professionals assess:

• Presence and location of the pregnancy
• Gestational age
• Number of fetuses
• Fetal growth
• Fetal position
• Fetal movement
• Fetal heart activity
• Placental location
• Amniotic fluid
• Selected fetal anatomy
• Certain pregnancy-related concerns

The timing and type of ultrasound depend on the individual pregnancy and the purpose of the examination.

ACOG notes that prenatal ultrasound may be standard, limited or specialized depending on the clinical question.

What Can a 3D/4D Obstetric Scan Show?

A 3D/4D obstetric scan can provide additional views of fetal structures and movement, but the information obtained varies according to the pregnancy and examination conditions.

Fetal Anatomy

Three-dimensional imaging can provide additional perspectives of selected fetal structures when suitable images can be obtained.

Fetal Movement

4D imaging can display movement in real time, allowing dynamic visualization during the scan.

Fetal Position

The position of the fetus can affect the images obtained and may also be part of the assessment during obstetric ultrasound.

Placenta and Amniotic Fluid

Obstetric ultrasound can help assess placental position and the amount of amniotic fluid around the fetus.

Fetal Growth

Ultrasound can be used to assess fetal growth and measurements appropriate to the examination and stage of pregnancy.

What Is the Difference Between 2D, 3D and 4D Ultrasound?

The main difference is how the ultrasound information is displayed.

3D and 4D imaging do not replace the need for appropriate medical assessment. The examination should be selected according to the clinical purpose.

When Is a 3D/4D Pregnancy Scan Done?

There is no single gestational week that is appropriate for every 3D/4D scan.

The most suitable timing depends on:

• Purpose of the examination
• Gestational age
• Fetal position
• Amount of amniotic fluid
• Placental position
• Maternal body characteristics
• Imaging conditions
• Doctor's recommendation

A standard obstetric ultrasound may be scheduled according to routine prenatal care, while specialized examinations are performed when a specific clinical question needs to be addressed.

ACOG notes that a standard prenatal ultrasound is commonly performed around 18–22 weeks, although timing varies by clinical circumstances.

For a 3D/4D examination specifically, the visibility of the fetus can vary significantly from one pregnancy to another, so the best time should be determined according to the reason for the scan and the advice of the treating healthcare professional.

Is 3D/4D Ultrasound Safe During Pregnancy?

Diagnostic obstetric ultrasound is considered safe when appropriately performed for medical purposes by trained professionals.

Ultrasound does not use ionizing radiation. However, ultrasound energy can produce biological effects under certain exposure conditions, which is why professional organizations recommend prudent use and keeping exposure as low as reasonably achievable while obtaining the necessary diagnostic information.

The AIUM recommends that fetal ultrasound examinations be performed by appropriately trained and credentialed professionals and discourages nonmedical or unnecessary ultrasound exposure.

For this reason, 3D/4D ultrasound should be treated as a medical imaging examination rather than simply a keepsake or entertainment scan.

Does a 3D/4D Obstetric Scan Use Radiation?

No. Ultrasound does not use ionizing radiation.

Obstetric ultrasound uses high-frequency sound waves to create images of the fetus and pregnancy-related structures.

This is different from:

• X-Ray: X-rays
• CT Scan: X-rays
• MRI: Magnetic fields and radio waves

Even though ultrasound does not use ionizing radiation, it should still be used appropriately and for a medical purpose.

Is a 3D/4D Pregnancy Scan Painful?

A routine abdominal obstetric ultrasound is generally non-invasive and is usually not painful.

During the examination, ultrasound gel is applied to the abdomen and a transducer is moved over the skin.

You may feel some pressure while images are being obtained.

The level of pressure or discomfort can vary depending on:

• The position of the fetus
• The area being examined
• The amount of pressure needed to obtain images
• Your individual comfort

Tell the healthcare professional if you experience significant discomfort during the examination.

How Should You Prepare for a 3D/4D Obstetric Scan?

Preparation depends on the type and timing of the obstetric ultrasound.

Not every pregnancy scan requires the same preparation.

Before your appointment, ask the centre whether you should:

• Drink water before the scan
• Have a partially or fully filled bladder
• Avoid eating or drinking for a particular period
• Bring previous pregnancy scan reports
• Bring your doctor's prescription or referral

Do not assume that the preparation for one pregnancy scan is the same as another.

Bring Previous Reports

Previous ultrasound reports can provide useful clinical context for your healthcare team, particularly when follow-up imaging is being performed.

What Happens During a 3D/4D Obstetric Scan?

Understanding the process can help you feel prepared.

1. Patient Information

The healthcare professional may ask about:

• Gestational age
• Previous scans
• Medical history
• Pregnancy history
• Current concerns
• Doctor's referral

2. Positioning

You will usually lie comfortably on the examination bed.

3. Ultrasound Gel

A layer of ultrasound gel is applied to the abdomen.

4. Image Acquisition

The transducer is moved across the abdomen to obtain images.

5. 3D/4D Imaging

When suitable images can be obtained, the ultrasound system may reconstruct three-dimensional views and, with 4D imaging, display movement in real time.

6. Additional Measurements

Depending on the examination, the healthcare professional may obtain measurements and assess specific fetal or pregnancy-related structures.

Why Can 3D/4D Ultrasound Images Look Different From One Pregnancy to Another?

The quality and appearance of 3D/4D images can vary considerably between pregnancies.

Factors that can influence image quality include:

• Fetal position
• Gestational age
• Fetal movement
• Amount of amniotic fluid
• Placental location
• Maternal body characteristics
• Position of the fetus relative to the ultrasound probe

Therefore, a less clear 3D/4D image does not automatically indicate a problem with the pregnancy.

The diagnostic value of an obstetric ultrasound is not determined solely by how clear a 3D facial image appears.

What Is Doppler Ultrasound in Pregnancy?

Doppler ultrasound is a specialized ultrasound technique used to evaluate blood flow.

During pregnancy, Doppler techniques may be used in selected clinical situations to assess blood flow in areas such as the:

• Umbilical cord
• Placenta
• Fetal circulation
• Maternal blood vessels

Doppler is not required for every pregnancy scan.

Its use should be based on the clinical indication and performed appropriately by trained professionals. The AIUM recommends that Doppler techniques be used judiciously, particularly during early pregnancy.

Can a 3D/4D Scan Detect All Birth Defects?

No. No ultrasound examination can detect every fetal abnormality.

Ultrasound can help identify many anatomical findings, but some abnormalities may be difficult to detect depending on:

• Gestational age
• Fetal position
• Image quality
• Type of examination
• Nature of the abnormality
• Clinical circumstances

RadiologyInfo notes that obstetric ultrasound cannot identify all fetal abnormalities. Further testing may sometimes be required when there is a clinical or laboratory concern.

A normal ultrasound is reassuring, but it does not guarantee that every possible condition has been ruled out.

Is 3D/4D Ultrasound the Same as an Anomaly Scan?

No. They are related to pregnancy imaging but should not automatically be considered the same examination.

An anomaly scan, often performed during the second trimester, is a detailed ultrasound examination intended to assess fetal anatomy and look for certain structural abnormalities.

A 3D/4D scan refers primarily to the way ultrasound data is reconstructed and displayed.

3D or 4D imaging may sometimes be used as part of a specialized obstetric examination, but 3D/4D imaging does not replace a clinically appropriate detailed fetal anatomical examination.

The examination you need should be based on your obstetrician's recommendation.

3D/4D Ultrasound vs Standard Pregnancy Ultrasound

Both are ultrasound examinations, but they may serve different purposes.

The most appropriate examination is the one that answers the medical question your doctor needs addressed.

What Happens After a 3D/4D Obstetric Scan?

After the examination, the images and findings are reviewed as part of the diagnostic process.

The interpretation may be considered together with:

• Gestational age
• Previous ultrasound findings
• Maternal medical history
• Pregnancy history
• Clinical findings
• Laboratory results
• Other investigations

Your treating obstetrician or appropriate healthcare professional can explain what the findings mean for your pregnancy.

If additional testing or follow-up ultrasound is recommended, it does not necessarily mean that something is wrong. Follow-up may simply be needed to obtain additional views or monitor a finding over time.
