(2) Ultrasound-guided amniocentesis to diagnose fetal chromosomal abnormalities.
(3) Ultrasonic monitoring of fetal growth and abnormal fetal position.
(4) Using ultrasound to measure the length of cervix to predict premature delivery and labor time.
(5) Color Doppler ultrasound assisted diagnosis of fetal intrauterine hypoxia.
(6) Diagnosis of various pregnancy complications, such as ectopic pregnancy, placenta previa and chronic placental abruption. It has a high level of ultrasonic diagnosis.
