How many weeks of pregnancy can one have a 4D ultrasound?

Patient's question:

Pregnant for 15 weeks, want to do a 4D ultrasound, but don't know when to do it appropriately. Want to ask how many weeks pregnant can you do a 4D ultrasound?

Doctor's answer:

Hello
According to your situation, you can have a 4D ultrasound examination after the fourteenth week of pregnancy. If the 4D ultrasound cannot identify some issues, amniocentesis can be performed for further diagnosis.
Generally, doctors recommend that patients with risk signs of prenatal examination should maintain a reasonable diet, avoid spicy and stimulating as well as cold foods. Additionally, patients should create an environment that promotes emotional stability and stress relief.
Wishing you a healthy delivery.
