【摘要】：目的探討實時動態(tài)四維時間-空間關(guān)聯(lián)成像技術(shù)(STIC)在胎兒心臟畸形輔助診斷中的應用及其診斷準確率。方法選取超聲心動圖篩查出胎兒先天性心臟病可疑的孕婦,再應用STIC技術(shù)進行數(shù)據(jù)采集、脫機分析。對終止妊娠或娩出后死亡胎兒,以尸檢病理診斷為確診結(jié)果;對活產(chǎn)胎兒以新生兒超聲診斷為確診結(jié)果。比較實時四維超聲STIC和二維超聲對胎兒心臟畸形診斷的準確率。結(jié)果產(chǎn)前篩查人群12 782例,納入受試對象217例,有效對象203例,其中112例經(jīng)引產(chǎn)后尸解病理證實或上級三甲醫(yī)院超聲確診,其余娩出的活產(chǎn)胎兒經(jīng)超聲或CT、MRI明確診斷。超聲心動圖診斷心臟畸形的準確率為94.09%,漏診率為4.43%,誤診率為1.48%;四維超聲STIC診斷心臟畸形的準確率為98.52%,漏診率為0.99%,誤診率為0.49%;四維超聲STIC診斷心臟畸形的準確率高于超聲心動圖(χ~2=5.61,P0.05),漏診率低于超聲心動圖(χ~2=4.58,P0.05),而漏診率比較差異無統(tǒng)計學意義(χ~2=0.25,P0.05)。結(jié)論實時四維超聲STIC技術(shù)在胎兒心臟畸形輔助診斷中具有較好的臨床應用價值,有助于彌補二維超聲診斷不完善、不精確的缺憾,提高了產(chǎn)前胎兒心臟畸形診斷的準確性,從而為產(chǎn)前篩查提供了更加可靠的科學依據(jù)。
[Abstract]:Objective to investigate the application of real-time dynamic four-dimensional spatio temporal correlation imaging (STIC) in the diagnosis of fetal cardiac malformation and its diagnostic accuracy. Methods the pregnant women with suspected fetal congenital heart disease were screened by echocardiography, and STIC technique was used to collect and analyze the data. On the termination of pregnancy or death of the fetus after delivery, diagnosis results in autopsy pathology diagnosis; to live births to the diagnosis of neonatal ultrasound diagnosis. The accuracy of real time four dimensional ultrasound STIC and two-dimensional ultrasound in the diagnosis of fetal heart malformation was compared. The results of prenatal screening population in 12782 cases, the subjects included 217 cases, effective 203 cases, 112 cases were confirmed by autopsy were diagnosed with pathology or superior hospital, the rest of the delivery of live births by ultrasound or CT, MRI diagnosis. The accurate rate of diagnosis of heart malformation echocardiography was 94.09%, the misdiagnosis rate was 4.43%, the misdiagnosis rate was 1.48%; the accuracy rate of STIC diagnosis of four-dimensional ultrasound cardiac malformation was 98.52%, the misdiagnosis rate was 0.99%, the misdiagnosis rate was 0.49%; the accuracy rate of four-dimensional ultrasound diagnosis of cardiac malformations was higher than that of STIC echocardiography (x ~2=5.61, P0.05), the rate of misdiagnosis is lower than echocardiography (~2=4.58, P0.05), and the misdiagnosis rate was no significant difference (~2=0.25, P0.05). Conclusion the real-time four-dimensional STIC technology has good clinical application value in diagnosis of fetal cardiac malformations, help compensate for the two-dimensional ultrasound diagnosis of incomplete and uncertain defects, improve the accuracy of prenatal diagnosis of fetal cardiac malformations, thus providing a more reliable basis for prenatal screening.

【正文快照】： 先天性心臟病(congenital heart disease,CHD)是臨床上一種常見胎兒畸形,流行病學調(diào)查研究顯示胎兒期發(fā)生率約0.4%~1.3%[1],且大多預后不佳,故而CHD產(chǎn)前診斷對改善妊娠的結(jié)局意義重大。目前,胎兒超聲心動圖檢查已成為產(chǎn)前篩查CHD的首選方法,但是由于檢查受宮內(nèi)條件限制,以及胎，
