“…A larger prospective study assessing the accuracy of Crystal Vue in the antenatal diagnosis of EA in a high‐risk group is warranted before clinical implementation of the technique may be proposed. Finally, we have not attempted any formal comparison with postprocessing 3D techniques from other manufacturers, which was beyond the scope of the current paper. The contrast‐enhancement properties of Crystal Vue make it suitable for the antenatal evaluation of hyperechoic structures such as the fetal esophagus.…”

Objective To evaluate the feasibility of antenatal direct visualization of normal and abnormal fetal esophagus using three‐dimensional ultrasound (3D‐US) with Crystal Vue rendering technology. Methods Between February and April 2018, 3D‐US volumes were collected from a non‐consecutive series of singleton pregnancies, referred for clinically indicated detailed prenatal ultrasound at 19–28 weeks' gestation to one of two fetal medicine units in Italy. 3D volumes were acquired from a midsagittal section of the fetal thorax and upper abdomen with the fetus lying in supine position. Postprocessing with multiplanar mode was applied to orientate the volume and identify the esophagus. The region of interest was angled by approximately 30° to the spine and its thickness was adjusted in order to optimize visualization of the intrathoracic and intra‐abdominal course of the esophagus. Crystal Vue software was used for image rendering of the fetal trunk in the coronal plane. Postnatal follow‐up was available in all cases. Results During the study period, 91 pregnancies met the inclusion criteria and were recruited. The study cohort included two pregnancies with suspicion of esophageal atresia due to suboptimal visualization of the stomach. Of the 89 cases with normal stomach on two‐dimensional (2D) imaging, 3D‐US with Crystal Vue rendering technology allowed direct evaluation of the whole course of the esophagus in 74 (83.1%). In the two cases with small or absent stomach bubble on 2D imaging, esophageal atresia was demonstrated antenatally on 3D Crystal Vue imaging and was confirmed postnatally. The mean time required for offline postprocessing and visualization of the esophageal anatomy was 4 min. Conclusions Using 3D‐US with Crystal Vue rendering, it is possible to visualize antenatally the normal fetal esophagus and demonstrate presence of esophageal atresia. This should facilitate prenatal counseling and management of cases with suspected esophageal atresia. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

“…On combining the HDlive flow silhouette mode and HDlive silhouette mode, we could observe overlapping blood vessels, facilitating vitreous-like clarity of the fetal heart simultaneously with a transparent core. 33,36,37 The holography-like blood flow imaging of the fetal heart is the main merit of the system (Fig. 4).…”

“…As cutting-edge technology, the HDliveFlow silhouette mode provides vitreous-like clarity of fetal heart blood flow and gynecologic tumors. [33][34][35][36][37][38] The core is shown as semitransparent while preserving the outline and borders of blood flow. Thus, it is possible to obtain holographic images of blood flow of the fetal heart and tumor vascularity, being its unique feature.…”

The HDlive flow silhouette mode is the latest technology to demonstrate vitreous-like clarity of blood flow and can preserve and delineate the outline and borders of the blood flow while showing its core as semitransparent. Therefore, holographic visualization of the fetal cardiac blood flow can be achieved. We can choose the combination of the HDlive flow or HDlive flow silhouette mode with glass-body rendering mode or HDlive silhouette mode for evaluation of the fetal heart. We can also evaluate the fetal heart from any direction, especially using five special views (frontal, spatial three-vessel, panoramic, posterior, and right lateral views). In this paper, HDlive flow silhouette mode characteristics of the normal fetal heart and congenital heart anomalies are shown using various images. The HDlive flow silhouette mode may help evaluate the normal fetal heart and diagnose congenital heart anomaly during pregnancy as an adjunctive diagnostic tool.

“…Crystal Vue™ is a context preserving post processing technique for 3D volumes which is not dissimilar to HDlive Silhouette (68)(69)(70)(71) and allows easier differentiation between tissues with different echogenicity by enhancing contrast. In this Expert Review we detail how 3D volumes are optimally obtained, which settings are used to optimize the anatomical sections and how post processing techniques -in this case Crystal Vue™ (32,36) -are used.…”
