Prediction of lethal pulmonary hypoplasia among high‐risk fetuses via 2D and 3D ultrasonography

Abstract

Among high-risk fetuses, US-FLW by 2D/3D and o/e-Tot-FLV by 3D ultrasonography were more accurate than 2D parameters for predicting LPH.

Fetal lung volume and pulmonary artery changes in congenital heart disease with decreased pulmonary blood flow: Quantitative ultrasound analysis

“…We chose sonographic FLV/EFW measurements to assess fetal lung development because previous studies suggested that this parameter was more accurate and feasible than other ultrasonographic parameters . The sonographic FLV/EFW parameter involved estimated fetal lung volumes measured by 3D‐US and adjusted for 2D‐US‐estimated fetal weight.…”

“…We chose sonographic FLV/EFW measurements to assess fetal lung development because previous studies suggested that this parameter was more accurate and feasible than other ultrasonographic parameters. 8,9 The sonographic FLV/EFW parameter involved estimated fetal lung volumes measured by 3D-US and adjusted for 2D-US-estimated fetal weight. Ruano et al 11 reported that the sensitivity and specificity of sonographic FLV/EFW for diagnosing pulmonary hypoplasia were 91.7% and 91.3%, respectively, and the accuracy was 91.4%.…”

“…7 Previous studies showed that FLV/EFW measured by sonography was useful for the prediction and diagnosis of pulmonary hypoplasia in congenital diaphragmatic hernia. 8,9 The McGoon index (MGI) measured by echocardiography has been widely used for evaluating the development status of pulmonary vessels in patients with CHD. 10 In this study, we used sonography to compare FLV/EFW and MGI values of fetuses with CHD-DPBF and normal fetuses.…”

A sonographic approach to the prenatal diagnosis of skeletal dysplasias

“…Although both techniques are effective, the stacked contour method is more reproducible than VOCAL . When fetal weight is taken into account, 3D fetal lung volume measurement performs better . Furthermore, it has been suggested that 3D ultrasound adds additional value to prenatal assessment of fetal skeletal dysplasias as it has the potential to delineate subtle skeletal anomalies .…”

“…35,36 When fetal weight is taken into account, 3D fetal lung volume measurement performs better. 37,38 Furthermore, it has been suggested that 3D ultrasound adds additional value to prenatal assessment of fetal skeletal dysplasias as it has the potential to delineate subtle skeletal anomalies. 39 Both 2D and 3D ultrasonography have limitations in the presence of a high maternal body mass index, excessive fetal movements and thoracic shadowing, particularly at later gestational ages.…”
