Four-dimensional ultrasound examination is an advanced medical imaging technique and an important prenatal check-up item during pregnancy. The optimal time for undergoing a four-dimensional color ultrasound is generally between 20 and 24 weeks of pregnancy, when the fetal organs and body structures have already formed, fetal movement is active, and the amniotic fluid volume is moderate. These factors facilitate clear visualization of the fetus by the physician using four-dimensional ultrasound.
Specifically, four-dimensional color ultrasound offers high resolution, allowing dynamic and three-dimensional observation of fetal structures, including limb and brain development. During this stage, four-dimensional ultrasound can accurately detect structural abnormalities in the fetus, such as developmental malformations of the limbs or brain.
In addition, four-dimensional ultrasound can assess fetal growth and development, screen for potential structural abnormalities, and provide expectant mothers and their families with more comprehensive prenatal information, aiding in subsequent prenatal preparations and decision-making. Therefore, it is recommended that pregnant women undergo routine four-dimensional color ultrasound examination between 20 and 24 weeks of pregnancy to ensure fetal health.
