4D Ultrasound Scans: What You Need to Know

Ultrasound scans have become a common part of prenatal care. They are used to check the health and development of the baby. But what are they? And what do you need to know about them? In this blog post, we will discuss 4D ultrasound scans. What they are, why they are done, and what you can expect from them. We will also answer some common questions that people have about 4D ultrasound scans from Core Physio.

What is a 4D Ultrasound Scan?

A 4D ultrasound scan is an advanced form of imaging technology used to view the unborn baby during pregnancy. It gives the clearest picture yet of your developing baby, and enables you to have a more interactive experience with them. The 4D images are generated using sound waves which are sent through the abdomen and bounced back off different parts of the baby’s body. These echoes are then collected by an array of receivers, giving us a detailed image of your baby in three-dimensional form.

Why Do Doctors Perform 4D Ultrasound Scans?

4D scans can provide doctors with important information about your developing baby’s anatomy and wellbeing. They check for birth defects, monitor the baby’s size and growth rate, and keep track of their position in the womb. 4D scans can also be used to check if the placenta is healthy and functioning properly. Doctors may use this information to determine if any interventions are needed during childbirth or labor.

What Can You Expect During a 4D Ultrasound Scan?

When you go for your 4D ultrasound scan, you will be asked to lie down on an examination table with your stomach exposed. The technician will then apply a warm, thick gel on your abdomen to allow for good contact between the transducer and skin. The transducer is then moved over your abdomen in order to capture images of the baby. The images are then displayed on a monitor so that you can see your unborn baby in three-dimensional form.

What Are the Risks?

Ultrasound scans are considered relatively safe, and there is no known risk associated with 4D ultrasound scans specifically. However, prolonged exposure to sound waves could possibly lead to over-heating of tissues. It is important to follow the safety guidelines set out by your doctor or technician when having your scan. This may include limiting the duration of the scan and avoiding frequent visits for repeat exams if not medically necessary.


In conclusion, 4D ultrasound scans have become an invaluable tool for medical professionals to assess fetal health and development during pregnancy. They provide detailed images of the baby that are highly beneficial to both parents and doctors. It is important to follow safety guidelines when undergoing a 4D ultrasound scan, but it is generally considered safe with no known risks. So if you have any questions or concerns about your pregnancy, be sure to ask your doctor about a 4D ultrasound scan. This advanced imaging technology could give you the insight and peace of mind you need during this special time.
