Abstract Ultrasonography has the advantages of safe, uninvasive, fast and reliable and practical. It is the first choice of imaging methods for obstetrics. In 11~13+6 weeks, ultrasonic measurement of fetal nuchal translucency(NT) thickness plays an important role in reducing perinatal birth defects, particularly in the fetal chromosomal abnormalities and structural abnormalities. With the continuous improvement of prenatal screening and prenatal diagnosis technology, the study on fetal NT thickness is becoming more and more deeply. Comprehensive domestic and foreign literature in recent years, the application of ultrasound in prenatal screening and prenatal diagnosis are reviewed in this paper.
