摘　　要：目的:探讨三维超声多平面显示模式在产前诊断胎儿结构畸形的应用价值。方法:总结40例产前超声检查时疑似胎儿结构畸形的胎儿,行多平面显示模式进行进一步检查,检查结果均于产后随访、CT、造影或引产后尸检得到证实。分析其检查的价值和技巧。结果:本组40例行产检疑似结构畸形的胎儿中,经产后随访、CT、造影或引产后尸检确诊者38例,误诊2例为没发生积水的重复肾者。其中确诊腭裂诊断20例,心脏结构畸形12例,胼胝体缺如3例,小脑蚓部缺失2例,马蹄肾1例。结论:产前超声诊断胎儿结构畸形,尤其是在有些二维影像难以显示的结构时,三维多平面成像可以提供更有价值的超声影像,增加超声医生的诊断信心[1,2]。Objective： To investigate the relevant value oi three-dimensional （3D） multi-slice view （MSV） mode of ultrasonography on fetal structural malformations when prenatal diagnosis. Methods： 40 fetuses, which were considered as suspicious fetal structural malformations after prenatal ultrasound examination, were selected for further analysis by the multi-slice view mode. The inspection result was proved by CT or radiography after born or necropsy after induced labor. Analysis was performed on the value and skill of 3D-MSV mode examination. Results： Among 40 suspicious cases, 38 fetuses were diagnosed fetal structural malformations. The other two misapplied cases were those with duplication of kidney without hydronephrosis. 50% （20/40） cases were diagnosed blade edge, 30% （12/40） were diagnosed heart defects, 7.5% （3/40） absence of callus, 5% （2/40） cauda cerebelli, 2.5% （1/40） horseshoe kidney. Conclusion： 3D-MSV mode provided more valuable ultrasonic image and strengthen the confidence of doctors, especially when tile structure was hardly displayed by bidimensional image.
