Objective To explore the application value of four dimensional color ultrasonography in prena-tal fetal malformation examination.Methods A total of eighty pregnant women who underwent prenatal fetal malformation examination in Xinjiang Shihezi Maternal and Child Health Hospital from December 2021 to De-cember 2023 were selected as the study objects.All pregnant women underwent four dimensional color ultra-sound examination in the second trimester(20-24 weeks),and comprehensive examinations were used as the gold standard.The diagnostic efficiency of four dimensional color ultrasonography in the diagnosis of fetal mal-formation was analyzed.Results The comprehensive examinations results showed that among the 80 pregnant women,13 cases of fetal malformation,accounting for 16.25%(13/80).The true positive cases and true negative cases were 11 and 65 respectively.The kappa value for the diagnosis of fetal malformation by four dimensional color ultrasonography and the comprehensive examinations results was 0.857,and the consistency was good.The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of prenatal deformi-ties of four dimensional color ultrasound were 95.00%(76/80),84.62%(11/13),97.01%(65/67),84.62%(11/13),97.01%(65/67).The coincidence rates of four dimensional color ultrasonography were 100.00%(3/3),100.00%(4/4),50.00%(1/2),100.00%(2/2)and 50.00%(1/2)for the diagnosis of limb malformations,facial malformations,heart malformations,nervous system malformations and lung malformations.Conclusion The four dimensional color ultrasonography has high diagnostic efficiency in the diagnosis of fetal malformations,and has certain clinical value in prenatal screening of fetal malformations.
