摘要
目的探讨表面三维成像(three-dimensional ultrasound surface,3-DUS)和断层超声显像(tomogramphy ultrasound imaging,TUI)这2种三维超声显示技术在诊断胎儿畸形的价值。方法应用3-DUS和TUI技术,进行1190例胎儿的三维超声检查。结果文中胎儿畸形发生率4.37%(52/1190),采用3-DUS诊断胎儿体表畸形阳性符合率97.14%(34/35),胎儿体内畸形阳性符合率23.53%(4/17)。TUI技术诊断胎儿体表畸形阳性符合率37.14%(13/35),胎儿体内畸形阳性符合率100%(17/17)。采用3-DUS、TUI技术、3-DUS和TUI技术联合诊断胎儿畸形敏感性分别为73.1%、57.7%、100%,特异性为99.1%、98.7%、99.9%。结论显示胎儿体表结构以3-DUS为主,显示胎儿体内结构以TUI技术为主,两者技术应该成为互补,有利提高产前胎儿畸形的检出率。
Objective The aim of this study was to assess the value of three-dimensional ultrasound (3-DUS) surface mode imaging and tomography ultrasound imaging (TUI) in the diagnosis of fetal malformations.Methods A total of 1190 fetuses were examined by TUI and 3-DUS surface mode imaging.Results The incidence of malformed fetuses was 4.37% (52/1190) in our study group.Of the 52 malformed fetuses,97.14% (34/35) of those with surface malformations and 25.53% (4/17) of those with internal malformations were found by 3-DUS surface mode imaging;in comparison,37.14% (13/35) of those with surface malformations and 100.00% (17/17) of those with internal malformations were revealed by TUI.The sensitivities of 3-DUS surface mode imaging,TUI and combination of TUI with 3-DUS surface mode imaging in diagnosing fetal malformations were 73.1 %,57.7 % and 100%,and their specificities were 99.1%,98.7% and 99.9%,respectively.Conclusion Fetal surface structures were displayed mainly by 3-DUS surface mode imaging,while internal structures chiefly by TUI.The complementation of TUI and 3-DUS surface mode imaging would help to improve the detection of fetal malformations.
