HDLiveSilhouette Inversion Mode in Diagnosis of Complete Hydatidiform Mole

Abstract

We present our experience of using the HDLive silhouette inversion mode to assess complete hydatidiform mole early in pregnancy. The HDLive silhouette inversion mode clearly depicted the number, size, and spatial position of molar vesicles, compared with conventional two-dimensional sonography or the HDLive inversion mode. Moreover, spatial relationships among molar vesicles, intrauterine anechoic fluid collection, and the uterine wall enabled the clear localization of the lesion. This technique provides new insights, and has the potential to supplement conventional two-dimensional sonography in the diagnosis of complete hydatidiform mole.

HDlive Flow Silhouette Mode for Fetal Heart

“…2), as well as that of peripheral blood vessels, placental abnormality, and gynecologic disorders, and so it is possible to not only spatially view these vessels but also visualize landmarks of adjacent structures. [24][25][26][27][28][29][30][31][32]…”

“…It allows more accurate assessments of the following: fetal heart and peripheral circulation, placental vasculature, and tumor vascularity in the presence of gynecologic disorders. [22][23][24][25][26][27][28][29][30][31][32] The use of HDlive to increase the resolution of 3D/4D color/power Doppler leads to a significant improvement in comparison with conventional 3D/4D color/power Doppler, facilitating clear visualization of fetal heart with great vessels, peripheral vessels, placental blood flow, and tumor blood flow in the presence of gynecologic disorders.…”

HDlive Flow for Diagnosis of Invasive Mole

“…The novel HDlive flow three-dimensional (3D) color/ power Doppler, HDlive flow with its adjustable light source facilitates spatial reconstruction of the fetal heart and associated vessels and the vascularity of tumors in gynecologic diseases. [2][3][4][5][6][7] The novel features of HDlive flow silhouette allow operators to distinguish between overlapping blood vessels and comprehend spatial relationships that exist among blood vessels and their surrounding structures. [8][9][10][11] To our best knowledge, no studies have been conducted on the HDlive flow or HDlive flow silhouette-based findings of an invasive mole.…”

HDlive Flow with HDlive silhouette mode in diagnosis of molar pregnancy

“…The third case of typical complete mole, diagnosed at 9 + 5 weeks, has been reported previously by our group. Color Doppler imaging depicted numerous small vesicles inside the mass surrounded by a well‐vascularized uterine myometrium (Figure a).…”

“…There have been several reports on the 3D ultrasound features of molar pregnancy in the first trimester; however, the spatial relationship between molar vesicular structures, fluid collection and surrounding vascularity remains unclear. In this study, the unique characteristics of the combination of HDlive Flow with HDlive silhouette mode allowed the observation of overlapping blood vessels, showed with vitreous‐like clarity the outline and borders of molar vesicles or cysts with a transparent core, and revealed fluid collection folds and curves with inner structures.…”
