摘　　要：目的:观察四维超声成像技术在胎儿体表畸形中的诊断价值。方法:选取我院200例产检孕妇,均于中、晚期接受二维与四维超声检查,以产后或引产病理检查为“金标准”,比较二维超声与四维超声诊断胎儿体表畸形准确性、灵敏度、特异度。结果:二维超声检查胎儿体表畸形灵敏度64.29%,特异度87.10%,准确性85.50%,Kappa值0.32;四维超声检查胎儿体表畸形灵敏度92.86%,特异度97.83%,准确性97.50%,Kappa值0.83;四维超声检查准确性、特异度、胎儿颜面部畸形检出率明显高于二维超声(P<0.05)。结论:相较于二维超声,四维超声成像技术诊断胎儿体表畸形准确性更高,能更有效检出胎儿颜面部畸形,具有重要应用价值。Objective:To observe the diagnostic value of four-dimensional ultrasound imaging technique for fetal external anomalies.Methods:200 pregnant women in the hospital were given two-dimensional and four-dimensional ultrasonography in the middle and late stages.With postpartum or induced labor pathological examination as the golden standard,the accuracy,sensitivity and specificity of two-dimensional ultrasound and four-dimensional ultrasound for diagnosis of fetal external anomalies were compared.Results:The sensitivity,specificity,accuracy and Kappa value of two-dimensional ultrasonography for fetal external anomalies were 64.29%,87.10%,85.50%and 0.32.However,those of four-dimensional ultrasonography were 92.86%,97.83%,97.50%and 0.83.The accuracy,specificity and detection rate of fetal external anomalies of four-dimensional ultrasonography were significantly higher than those of two-dimensional ultrasonography(P<0.05).Conclusion:Compared with two-dimensional ultrasound,the accuracy of four-dimensional ultrasound imaging technique is higher for diagnosis of fetal external anomalies.t can detect fetal external anomalies more effectively,with great application value.
