| 目的 探讨自动四维彩色容积超声在正常胎儿心脏检查中的应用价值。方法 对120例孕中期(18~23孕周)胎儿心脏进行四维容积扫查,在显示四腔心切面、启动彩色多普勒后采集胎儿胸部容积数据,利用超声自动多平面成像法自动获取3个诊断切面,分别为切面1(左心室流出道切面)、切面2(右心室流出道切面)及切面3(动脉导管弓切面),并采用超声断层显像法(TUI)显示所有切面的彩色血流图。对所有的容积数据进行分析并确定在每个容积数据中切面1~3是否正确显示。结果 通过自动四维彩色容积超声扫描,切面1~3的显示率分别为100%、96.67%、91.67%。切面1至少可在连续3个TUI图像上可靠显示,切面2和切面3均至少可在连续2个TUI图像上可靠显示。结论 自动四维彩色容积超声可自动获取胎儿心脏检查中所需的重要切面,显示率较高,并可观察相应切面的血流情况,显示效果良好。 |

| Objective To assess the application of automated four-dimensional (4D) volume color Doppler ultrasonography in normal fetal heart screening. Methods Four-dimensional volume color Doppler was acquired at the level of four chamber view level in 120 fetuses from 18 to 23 weeks of gestation. Three diagnostic planes including color Doppler information were retrieved by automated multiplanar imaging from the 4D volumes. The left ventricular outflow view (cardiac plane 1), the right ventricular outflow view (cardiac plane 2) and ductal arch view (cardiac plane 3) were acquired. Tomographic ultrasound imaging (TUI) was added to display all the three diagnostic planes. The data were then analyzed to determine whether cardiac planes 1-3 were displayed correctly in each volume. Results Automated 4D volume color Doppler ultrasonography displaying rate of cardiac plane 1, cardiac plane 2, cardiac plane 3 were 100%, 96.67% and 91.67%, respectively. Cardiac plane 1 was displayed at least three TUI plane, cardiac plane 2 was displayed at least two TUI plane, and cardiac plane 3 was displayed at least two TUI plane. Conclusion It is possible to acquire important planes of the fetal heart with automated 4D volume color Doppler ultrasonography and the visualization rate of the three diagnostic planes is fine. |
