目的利用超声容积自动测量(SonoAVC)技术和时间空间相关成像(STIC)技术研究胎儿心脏三维结构.方法利用STIC技术采集胎儿心脏的容积数据,对有引产或生后随访结果的32例胎儿心脏利用SonoAVC回顾性分析心脏容积数据,其中20例为正常胎儿,12例为复杂先天性心脏病胎儿.系统软件SonoAVC及ROI自动搜寻无回声区或低回声区,标记为不同的颜色;再用手动描记功能修正细节.结果心脏各房室腔及大血管能被系统识别分离,通过手动描记修正后,可得到心脏腔室及大血管的铸型图,4例大动脉转位、2例法洛四联征、1例三尖瓣下移畸形、1例右室双出口及20例正常胎儿均获得了满意的三维铸型图.结论 SonoAVC结合STIC技术能够显示胎儿心脏房室及大血管的大小、形态及三维空间关系,不仅有助于胎儿心脏畸形的诊断,而且在会诊及教学中可发挥更大的作用.

Objective To evaluate three dimensional fetal heart structure by sono-automatic volume count (SonoAVC) with spatio-temporal image correlation(STIC). Methods The heart volumes datas were acquired by STIC in 32 fetuses with postnatally confirmed diagnoses(20 cases of normal heart, 12 cases of complex congenital heart disease between 20 - 37 gestional weeks), then the volume datas were analyzed offline. SonoAVC software automaticly searched hypoechoic and anechoic structures, and assigned individual colors,and this can be corrected by manual splitting and/or removing and merging of individual segments.Results Individual segments of fetal heat could be separated,and digital casts were generated. The digital casts were obtained successfully in 4cases of transposition of the great arteries(TGA) ,2 cases of tetralogy of Follot,1 case of Ebstein's anomaly, 1 case of double-outlet right ventricle and 20 cases of normal heart.Conclusions Combination of STIC and SonoAVC can demonstrate the size, shape and connection of fetal cardiac cavities and great arteries in three dimensional spatial context. It has the potential both to help in obtaining strctural diagnostic,and to generate 3D visual displays for consultation and teaching.
