Application of Ultrasound in Prenatal Diagnosis of Birth Defects

Author(s): Qianqian Li, Li Guanghui

At present, prenatal diagnosis is simple, effective, uninvasive and repeatable, so that it has been recognized as the preferred method for prenatal screening of fetal malformations. Antenatal ultrasound has been widely used in clinic, andhas made a great contribution to the screening of fetal malformations.In recent years, dueto the standardization of the ultrasound and the increasing of intrauterine diagnosis technology by ultrasound-doctors, the birth of fetuses with abnormalities of central nervous system is decreasing year by year,and also the detection rate of fetuses with cardiovascular defects become higher and higher.As the ultrasound is widely used in prenatal intrauterine diagnosis, the safety of ultrasonography is also widely concerned.In China,the standard operation of the safety threshold of ultrasonic inspection in prenatal screening and diagnostic ultrasonography has been started.
