Theoretically, a cross-sectional image of any cardiac planes can be obtained from a STIC fetal heart volume dataset. We described a method to display 11 fetal echocardiographic planes from STIC volumes.
Fetal heart volume datasets were acquired by transverse acquisition from 200 normal fetuses at 15 to 40 weeks of gestation. Analysis of the volume datasets using the described technique to display 11 echocardiographic planes in the multiplanar display mode were performed offline.
Volume datasets from 18 fetuses were excluded due to poor image resolution. The mean visualization rates for all echocardiographic planes at 15-17, 18-22, 23-27, 28-32 and 33-40 weeks of gestation fetuses were 85.6% (range 45.2-96.8%, N = 31), 92.9% (range 64.0-100%, N = 64), 93.4% (range 51.4-100%, N = 37), 88.7%(range 54.5-100%, N = 33) and 81.8% (range 23.5-100%, N = 17) respectively.
Overall, the applied technique can favorably display the pertinent echocardiographic planes. Description of the presented method provides a logical approach to explore the fetal heart volumes.
从理论上讲,任何心脏平面的横截面图像都可以从STIC胎儿心脏容积数据集中获取。我们描述了一种从STIC容积中显示11个胎儿超声心动图平面的方法。
对200例孕15至40周的正常胎儿进行横向采集,获取胎儿心脏容积数据集。使用所描述的技术对容积数据集进行分析,以在多平面显示模式下显示11个超声心动图平面,并进行离线分析。
由于图像分辨率差,排除了18例胎儿的容积数据集。孕15 - 17周、18 - 22周、23 - 27周、28 - 32周和33 - 40周胎儿所有超声心动图平面的平均显示率分别为85.6%(范围45.2 - 96.8%,N = 31)、92.9%(范围64.0 - 100%,N = 64)、93.4%(范围51.4 - 100%,N = 37)、88.7%(范围54.5 - 100%,N = 33)和81.8%(范围23.5 - 100%,N = 17)。
总体而言,所应用的技术能够很好地显示相关的超声心动图平面。所提出方法的描述为探索胎儿心脏容积提供了一种合理的方法。
