To evaluate prospectively the performance of software that automatically retrieves, from a three-dimensional (3D) volume of the fetal chest, three diagnostic cardiac planes in the second trimester of pregnancy.
3D static volumes of the fetal chest were acquired at the level of the four-chamber view in 72 fetuses between 18 and 23 weeks of gestation. Standardization of 3D volumes was performed in Plane A (the reference plane: four-chamber view) alone. Tomographic ultrasound imaging (TUI) was added to the display of each diagnostic plane. The left ventricular outflow plane (Cardiac plane 1: five-chamber view, aorta), the right ventricular outflow plane (Cardiac plane 2: pulmonary artery) and the abdominal circumference plane (Cardiac plane 3: abdominal circumference, stomach) were retrieved by the software from the 3D volumes and the data were analyzed to determine whether Cardiac planes 1-3 were displayed correctly in each volume.
The automated software displayed, in at least one TUI plane, target Cardiac plane 1 in 94.4% of volumes, target Cardiac plane 2 in 91.7% of volumes and target Cardiac plane 3 in 97.2% of volumes.
Our results validate the concept of automated sonography and its potential clinical applicability.
前瞻性评估一款软件的性能，该软件可从胎儿胸部的三维（3D）容积中自动获取妊娠中期的三个诊断性心脏平面。
在72例妊娠18至23周胎儿的四腔心切面水平获取胎儿胸部的3D静态容积。仅在平面A（参考平面：四腔心切面）对3D容积进行标准化。在每个诊断平面的显示中添加断层超声成像（TUI）。软件从3D容积中获取左心室流出道平面（心脏平面1：五腔心切面，主动脉）、右心室流出道平面（心脏平面2：肺动脉）和腹围平面（心脏平面3：腹围，胃），并对数据进行分析，以确定心脏平面1至3在每个容积中是否正确显示。
自动软件在至少一个TUI平面中，在94.4%的容积中显示目标心脏平面1，在91.7%的容积中显示目标心脏平面2，在97.2%的容积中显示目标心脏平面3。
我们的结果验证了自动超声检查的概念及其潜在的临床适用性。
