Abstract：Objective To explore the clinical value of real-time three-dimensional ultrasound surface combined with transparency imaging mode in the diagnosis of fetal malformations.Methods 202 pregnant women who were given twodimensional and three-dimensional ultrasound examination from July 2014 to July 2015 in our hospital were selected as the research objects,all pregnant women were pregnant for 16-38 weeks,and were diagnosed by three-dimensional ultrasound surface and transparent imaging.The accuracy,specificity and sensitivity of two-dimensional and three-dimensional ultrasound diagnosis were analyzed and calculated.Results 24 malformations were detected in this study,16 lesions(66.67%)were correctly diagnosed by two-dimensional ultrasound,8 lesions(33.33%)were missed diagnosis;21 lesions(87.50%)were correctly diagnosed by three-dimensional ultrasound,3 lesions(12.50%)were missed diagnosis. There was significant difference in the correct diagnosis rate between two-dimensional and three-dimensional ultrasound diagnosis(P＜0.05).202 pregnant women examined in this study,52 cases of malformations were confirmed after birth and induction of labor,among them,12 cases were diagnosed by two-dimensional ultrasound,190 cases had no fetal malformation,there were 9 cases of fetal malformation and 193 cases of no fetal malformation after induced labor or after birth.16 cases of fetal malformation were diagnosed by three-dimensional ultrasound,186 cases had no fetal malformation,there were 15 cases of fetal malformation and 187 cases of no fetal malformation after induced labor or after birth.The sensitivity of two-dimensional ultrasound diagnosis was lower,and the sensitivity was 90.35%,the specificity was 94.74%,and the accuracy was 100.00%.Conclusion The real-time three-dimensional ultrasound surface and transparent imaging mode can make up for the deficiency of two-dimensional ultrasound in diagnosis of fetal malformations,improve the diagnosis accuracy of fetal malformations and play an active role in promoting prenatal diagnosis of fetal malformations,which is worthy of clinical promotion and application.
