Abstract Objective To explore the application value of prenatal four-dimensional ultrasound in the diagnosis of fetal malformations. Methods A total of 910 pregnant women who underwent antenatal check-ups in our hospital were included as research subjects.Compare the detection results of facial,central nervous system,digestive system,cardiac system,urinary system,limb skeletal system,skin,chest and abdominal cavity deformities by two-dimensional ultrasound and four-dimensional ultrasound.With the follow-up results as the standard,the accuracy of the two groups in diagnosing fetal abnormalities was compared. Results Among 910 pregnant women,902 had single pregnancy and 8 had twin pregnancy.A total of 58 malformed fetuses were detected,of which 48 had terminated their pregnancy,and 10 continued their pregnancy.The follow-up confirmed 64 malformations,39 fetal malformations were detected by two-dimensional ultrasound,the detection rate was 60.94%,and 55 fetal malformations were detected by four-dimensional ultrasound,the detection rate was 85.94%,and the detection rate of four-dimensional ultrasound was significantly higher than that Two-dimensional ultrasound（P<0.05）. Conclusion Compared with two-dimensional ultrasound,prenatal four-dimensional ultrasound can improve the efficiency and accuracy of screening for fetal malformations and is worthy of clinical promotion.
