Patient information: Age: 27 Gender: Female
nt at 11-13+6 It is best to check in between weeks.
nt examination is mainly to scan the thickness of the fetal neck zona pellucida by color Doppler ultrasound to preliminarily rule out fetal chromosomal abnormalities. It is a special method to assess the fetus suffering from Down syndrome. Generally, the best examination time is 11-13+6 Between weeks. The fetus is small before 11 weeks and cannot be detected by B-ultrasound. After 14 weeks, the fetal subcutaneous water may be covered by the developing lymphatic system, which makes it difficult to obtain accurate data. Early or late will affect the test results.
It is recommended that pregnant mothers go to the obstetrics and gynecology department of a regular hospital for examination within the specified time, and usually pay attention to avoid fatigue, relax, ensure rest and sleep, eat more fresh vegetables and fruits, and eat less spicy, cold, and greasy food.
Recommendations are for reference only. If the problem is serious, please go to the hospital for detailed examination
