What is 3D Scan in Pregnancy?


A 3D scan in pregnancy is a medical imaging technique that uses ultrasound technology to create a 3D image of a developing fetus. This type of scan provides more detailed images of the fetus than a traditional 2D ultrasound, allowing healthcare providers to better evaluate fetal development and identify potential issues.

Why is it performed?

A 3D scan may be performed during pregnancy for a variety of reasons, including:

Confirming the pregnancy and determining the gestational age of the fetus

Checking for multiple pregnancies

Assessing fetal growth and development

Evaluating the placenta, amniotic fluid levels, and umbilical cord

Identifying potential birth defects or abnormalities

Providing reassurance to parents about their developing baby

How to prepare?

Preparation for a 3D scan in pregnancy is similar to that of a traditional 2D ultrasound. Patients may be asked to drink fluids before the scan to fill their bladder, which can help provide better images. Patients should also wear comfortable, loose-fitting clothing that can be easily removed or adjusted.

What to expect?

During a 3D scan in pregnancy, the patient will lie down on an examination table, and a healthcare provider will apply a gel to the patient’s abdomen. The provider will then use a handheld device called a transducer to take images of the fetus from different angles. The images are then processed to create a 3D image of the fetus.

Myth and Fact

Myth: 3D scans in pregnancy are harmful to the developing fetus.

Fact: 3D scans in pregnancy use ultrasound technology, which is considered safe for both the mother and developing fetus. The procedure is non-invasive and does not use ionizing radiation.

Myth: 3D scans in pregnancy can accurately predict the gender of the baby.

Fact: While 3D scans can provide detailed images of the fetus, they are not always accurate in determining the gender of the baby. Gender determination is typically done through a separate ultrasound or blood test.

Myth: 3D scans in pregnancy can diagnose all fetal abnormalities.

Fact: While 3D scans can identify many fetal abnormalities, they may not be able to detect all conditions. Additional testing may be necessary to diagnose certain abnormalities.


Q: Are 3D scans in pregnancy covered by insurance?

A: Coverage for 3D scans in pregnancy varies by insurance plan. Patients should check with their insurance provider to determine coverage.

Q: How long does a 3D scan in pregnancy take?

A: The length of a 3D scan in pregnancy can vary depending on the position of the fetus and the quality of the images obtained. Typically, the procedure takes between 20-30 minutes.

Q: Is there any discomfort during a 3D scan in pregnancy?

A: Most patients do not experience any discomfort during a 3D scan in pregnancy. The gel applied to the abdomen may feel slightly cool, but should not cause any pain or discomfort.
