目的探讨四维超声多剖面容积成像技术（oblique view imaging，OVIX）诊断胎儿先天性心脏病的产前筛查价值。方法对50例正常胎儿及23例先天性心脏病胎儿用二维超声及OVIX技术进行图像比对。结果50例正常胎儿及23例先天性心脏病获得44（44/50）和20（20/23）合格的容积图像，能在实时状态下或图像处理后，清楚和直观显示任意切面的正常或异常心脏容积图像。结论 OVIX辅助超声心动图，是胎儿先天性心脏病产前筛查的有效检测手段，但仍需有经验的医师结合二维图及血流图明确诊断。“,”Objective Discuss the four-dimensional ultrasound oblique view imaging (OVIX)in the diagnosis of the value of prenatal screening of fetal congenital heart disease.Methods 50 cases of normal fetus and 23 cases of congenital heart disease with two-dimensional ultrasound and oblique view imaging .Results 50 cases of normal fetus and 23 cases of congenital heart disease get 44 (44/50) and 20 (20/23) of qualified volume images, can be in real time or after image processing, clear and intuitive display any aspect of normal or abnormal heart volume images.Conclusion OVIX auxiliary echocardiography, is an ef ective detection methods of prenatal screening of congenital heart disease in fetus, but stil need to be experienced doctors figure diagnosis combined with two-dimensional graph and blood flow.
