Abstract
Objective To investigate the clinical value of two dimensional ultrasound combined with four dimensional ultrasound in the prenatal diagnosis of fetal malformation .Method 1 298 Cases with late pregnant women who accepted prenatal screening were selected .Two dimensional ultrasound and four dimensional ultrasound were used in the diagnosis of fetal malformation .After the delivery , the diagnostic accuracy of single ultrasound and combined ultrasound examination was analyzed .Results In the diagnosis of fetal malformation , the sensitivity of four dimensional ultrasound was higher than that of two dimensional ultrasound , but the difference was not significant ( P>0 .05 ) .The specificity and the accuracy of four dimensional ultrasound were significantly higher than those of two dimensional ultrasound .The sensitivity , specificity , and accuracy of two dimensional ultrasound combined with four dimensional ultrasound were all significantly higher than those of two dimensional ultrasound,or four dimensional ultrasound,and the differences were significant (P <0.05).In thediagnosis of fetal surface malformations,the specificity and accuracy of four dimensional ultrasound were higherthan those of two dimensional ultrasound.The sensitivity of two dimensional ultrasound combined with fourdimensional ultrasound was higher than that of four dimensional ultrasound , but the differences were notsignificant (P >0.05).The sensitivity of four dimensional ultrasound or two dimensional ultrasound combinedwith four dimensional ultrasound was significantly higher than that of two dimensional ultrasound .The specificityand accuracy of two dimensional ultrasound combined with four dimensional ultrasound were significantly higherthan those of two dimensional ultrasound and four dimensional ultrasound ,and the differences were significant(P <0.05).Conclusion Two dimensional ultrasound combined with four dimensional ultrasound cansignificantly improve the prenatal diagnostic accuracy of fetal malformations ,which has a high clinical value andis worthy to be widely used in clinic.关键词
