Three-dimensional HDlive rendering images of the TRAP sequence in the first trimester: reverse end-diastolic umbilical artery velocity in a pump twin with an adverse pregnancy outcome

Three-dimensional ultrasonography by means of HDlive rendering in the first trimester of pregnancy: A pictorial review

“…In addition, HDlive can be used in multiple pregnancy with a clear definition of the "lambda sign" while evaluating chorionicity ( Figure 7). Currently, only two cases of prenatal 3D ultrasound diagnosis of the twin reversed arterial perfusion (TRAP) sequence in the first trimester (at 11 weeks and 4 days and at 13 weeks) have been described (25)(26)(27). In these two cases, conventional 3D ultrasound assisted in confirming the diagnosis and evaluating the extent and severity of structural anomalies in the acardiac fetus.…”

“…Notwithstanding, near-fetoscopic images of the TRAP sequence in the first trimester were obtained by employing the 3D HDlive rendering mode. In particular, 3D HDlive rendering images of the acardiac fetus seemed to be more readily discernible than those obtained by 2D and conventional 3D sonography because the 3D HDlive rendering provided a natural and anatomically realistic appearance of the acardiac fetus (25)(26)(27). HDlive has been shown to improve our understanding of neurobehavioral development in twins and assist in the investigation of inter-twin temperament and relationship (28,29).…”

“…Recent publications, most of them focused in obstetrics, show that HDlive provides a much more natural and realistic appearance of the normal embryo, 10,11,13,14,22,24 fetuses, 10,11,[13][14][15][16]22,23 their facial expressions, 11,13,15,16,22,24,25 cases of fetal abnormalities: acrania/exencephaly; 11,13,22,25 cyclopia with proboscis; 27 cystic hygroma; 22,26 Omphalocele; 11,13,14,22 multicystic kidney; 18 persistent cloaca, 28 siamese twins, 20 TRAP syndrome 29 and umbilical vein varix. 30 The most recent articles have been focused in visualizing special organs as heart, 31,32 the uvula and the soft palate.…”

HDlive of the Fetal Heart

“…[4][5][6][7][8][9] HDlive images obtained using both adjustable lighting and the new skin-like colors also present fetal, placental, and umbilical cord abnormalities with anatomically realistic features similar to those seen in gross specimens. [10][11][12][13][14][15][16][17][18] There have been only two reports on fetal HDlive echocardiographic evaluations of the normal fetal heart and congenital heart anomalies. 19,20 HDlive with spatiotemporal image correlation (STIC) provides entirely new visual experiences for obstetricians and pediatric cardiologists owing to the anatomically realistic depiction of normal and abnormal fetal cardiac structures of the beating heart.…”
