What is the difference between 3D and 4D prenatal ultrasound?

Patient's question:

I am three months pregnant. I see that some mothers get 2D ultrasounds, while others get 4D ultrasounds. What is the difference between 2D and 4D prenatal ultrasounds?

Doctor's answer:

Hello, it is recommended to follow medical advice in scheduling your time. At 3 months, it is suggested to decide on the implementation of NT screening via ultrasound. Generally, it is recommended to decide on 2D or 4D ultrasound between 4 to 6 months. 4D ultrasound is dynamic, so the results are clearer compared to 2D ultrasound. It is advised to ask specifically based on the local medical level, and then book early. However, avoid staying up late.
