The 4D ultrasound sheet can be viewed for diagnostic cues, baby indicators, and other abnormalities. The first thing a pregnant woman can do is to check the ultrasound prompts of the 4D ultrasound sheet. After the 4D ultrasound is done, the doctor will give a summarized diagnosis for the images that appeared during the ultrasound. If there are no abnormalities in the ultrasound, the baby is developing normally. Next, you can pay attention to the ultrasound report card to see if the baby’s biparietal diameter, head circumference, femur length, abdominal circumference, lateral ventricles, renal pelvis and other indicators are within the normal range. Pregnant women should also pay attention to whether the amniotic fluid is too much or too little, whether the function of the placenta is normal, and whether the baby’s umbilical cord is wrapped around the neck. If abnormalities are indicated, ask your doctor about the cause of the problem and the treatment plan to prevent the abnormalities from persisting and affecting your baby’s development.
