Introduction
Four-dimensional ultrasound, commonly referred to as 4D ultrasound, and "Down's child" generally refers to a child with Down syndrome. Under normal circumstances, 4D ultrasound cannot definitively detect whether a fetus has Down syndrome, but it can indicate whether the risk is high. 4D ultrasound is typically used for prenatal screening and monitoring fetal growth and development, providing detailed images. However, it is usually insufficient to determine whether the fetus has Down syndrome or other genetic disorders.

Four-dimensional (4D) ultrasound generally refers to 4D color Doppler ultrasound, while "Down's child" usually means a child with Down syndrome. In most cases, 4D ultrasound cannot definitively detect whether a fetus has Down syndrome, but it can indicate whether the risk is high. The specific analysis is as follows:

4D ultrasound is typically used for prenatal screening and monitoring fetal growth and development, providing detailed images. However, it is generally insufficient to determine whether the fetus has Down syndrome or other genetic disorders. Down syndrome is caused by chromosomal abnormalities, and affected individuals who survive often exhibit intellectual disability, characteristic facial features, and growth and developmental delays. A definitive diagnosis of Down syndrome usually requires specific prenatal screening tests, such as amniotic fluid cell chromosomal analysis or prenatal serum marker screening. However, it should be noted that 4D ultrasound can help identify high-risk cases. If a high risk is indicated, it is recommended to undergo the aforementioned prenatal screening tests for a definitive diagnosis.

Patients are advised to seek timely medical attention when experiencing any discomfort and to receive standardized treatment under the guidance of a physician, which may facilitate recovery.
