Introduction
Four-dimensional ultrasound examination is usually performed around 20 weeks of pregnancy. Specifically, this non-invasive medical procedure uses ultrasound technology to observe fetal development within the uterus, including the development of fetal organs, fetal size and morphology, placental position, amniotic fluid volume, and to detect any structural abnormalities in the fetus.
Under normal circumstances, a 4D ultrasound can be performed around 20 weeks of pregnancy. The detailed analysis is as follows:
A 4D ultrasound is a non-invasive medical examination that uses ultrasound technology to observe fetal development within the uterus, including organ development, fetal size and shape, placental position, amniotic fluid volume, and detection of structural abnormalities. It is typically conducted around the 20th week of pregnancy. Compared to 2D and 3D ultrasounds, 4D ultrasound provides clearer, more three-dimensional, and realistic images of the fetus, allowing doctors and parents to more intuitively observe and understand fetal development. During a 4D ultrasound, doctors can clearly see details such as the fetal face, hands, feet, and internal organs, and may even observe changes in the fetus's facial expressions, helping parents feel a closer connection to their unborn baby. A 4D ultrasound examination usually takes between 30 to 60 minutes, although the exact duration may vary depending on the hospital and physician scheduling. Prior appointment is generally required to ensure sufficient time for the pregnant woman's examination.
It is recommended to undergo the examination after urination to reduce bladder pressure on the uterus, thereby facilitating better visualization of the uterus.
