Introduction

In general, having a 4D ultrasound at 23 weeks of pregnancy is not too late. A 4D ultrasound is a medical examination method that uses high-frequency sound wave technology to scan the pregnant woman's abdomen in order to observe and evaluate the fetus's structure, development, and movement. The 4D ultrasound provides real-time dynamic images, clearly showing the fetal facial features, limb movements, and organ structures.

Generally, having a 4D color ultrasound at 23 weeks of pregnancy is not too late. The detailed analysis is as follows:

4D color ultrasound is a medical examination method that uses high-frequency sound wave technology to scan the pregnant woman's abdomen in order to observe and evaluate the fetus's structure, development, and movement. 4D color ultrasound provides real-time dynamic images, clearly showing the fetal facial features, limb movements, and organ structures. Performing a 4D ultrasound during pregnancy allows for assessment of fetal development and anatomy, observation of fetal activity and position, and prenatal screening. It is generally recommended to undergo 4D ultrasound between 20 and 24 weeks of gestation because, by this time, fetal development is relatively complete and the size remains moderate, allowing clearer visualization of fetal structures and organs. Conducting the scan too early or too late may lead to inaccurate results. Since 23 weeks falls within this optimal window, having a 4D ultrasound at this stage is timely.

If any abnormalities are detected during the 4D ultrasound, further evaluation is recommended to clarify the fetal condition and prevent delays in diagnosis and management.

Is swelling at 23 weeks of pregnancy normal?

In general, swelling at 23 weeks of pregnancy without other symptoms is considered normal. However, if it is accompanied by other adverse symptoms, it may indicate an abnormal condition.

What is the normal amniotic fluid index at 23 weeks of pregnancy?

At 23 weeks of gestation, an amniotic fluid index (AFI) between 5 and 25 cm is considered normal. The AFI in pregnant women is one of the key indicators used to assess fetal well-being and amniotic fluid volume. Although the normal range for AFI may vary slightly among individuals, it is generally accepted as 5–25 cm, and the index is measured via ultrasound examination.

At 23 weeks of pregnancy, is the fetal position already fixed?

Under normal circumstances, the fetal head position is usually not yet fixed at 23 weeks of gestation, and the fetus may still spontaneously change position. However, if the pregnant woman has limited uterine space, restricted fetal movement, or conditions such as uterine malformation, the fetal position may become relatively stable earlier, although changes are still possible. If there are any concerns, it is recommended to seek medical advice in advance. The detailed analysis is as follows:
