Objectives The main goal was to introduce the inversion mode as a new image analysis tool for the examination of fluid-filled structures using 3-dimensional ultrasonography during pregnancy. Methods Three-dimensional ultrasonography was performed on fetuses having fluid collections of noncardiac origin. Threshold adjustment was used to visually assign full transparency to voxels that were associated with fluid. A new postprocessing tool, called the inversion mode, was activated to transform this region of interest into opaque voxels. The morphologic appearance of fluid collections and their anatomic relationship to other organs were shown in this manner. Results Diagnostic features were shown by this technique in several fetuses with problems that included pleural effusion, duodenal atresia, urinary tract abnormalities, and hydrocephaly. Furthermore, the inversion mode also permitted surface reconstruction of an irregular pleural effusion that had close resemblance to results with the Virtual Organ Computer-Aided Analysis rotational slice technique. Acoustic shadowing was also documented as a potential technical limitation of this method. Conclusions The inversion mode can display scattered or contiguous fluid-filled structures in ways that can be very difficult or impossible to accurately characterize with conventional ultrasonography. It may be particularly helpful for the evaluation of multiple fluid-filled cysts or irregular fluid collections in the fetus.read more

TL;DR: 3D US and 4DUS provided additional information for the diagnosis of facial anomalies, evaluation of neural tube defects, and skeletal malformations and additional research is needed to determine the clinical utility of 3DUS and4DUS for the diagnoses of congenital heart disease, central nervous system anomalies and detection of fetal neurodevelopmental impairment assessed by abnormal behavior in high-risk fetuses.

Three-dimensional ultrasound evaluation of the placenta.
TL;DR: 3D ultrasound may be an important modality in future placental research, in the evaluation of feto-placental insufficiency in clinical practice, and in the prediction of fetal growth restriction and pre-eclampsia, although some limitations regarding the assessment of the placenta employing 3D ultrasound still remain unresolved.

Three-dimensional ultrasonography in prenatal diagnosis.
TL;DR: A comparison of the 2D and 3D techniques shows that 3D provides a diagnostic gain in a large percentage of cases, and this higher percentage resulted from the additional 3D surface reconstruction, the ability to view and evaluate the fetus from various angles, and the improved delineation of complex malformations.
