Background: Our objective is to present our first experience of adnexal tumors reconstructed employing the HDlive rendering mode.
Methods: Seven adnexal tumors (one case each of chocolate cyst, benign cystic teratoma, serous cystadenofibroma, and torsion of the hydrosalpinx, and three cases of ovarian cancer) were studied using the HDlive rendering mode.
Results: In the case of the chocolate cyst, the smooth inner wall with numerous tiny projections was clearly identified. In the case of benign cystic teratoma, a smooth hair ball inside the cyst was evident. In the case of the serous cystadenofibroma, a smooth, solid projection and relatively smooth septum were noted. In the three cases of ovarian cancer, numerous irregular papillae and irregular, thick septae were depicted. In the case of the bilateral hydrosalpinx with torsion of the right tube, different fluid contents were recognized.
Conclusion: The HDlive rendering mode provides anatomically realistic features such as macroscopic specimens for physicians and pathologists due to the complete depiction of the inner surface of the adnexal tumors.

This pictorial review describes the assessment of a great variety of types of congenital heart disease by three-dimensional ultrasonography with spatiotemporal image correlation using HDlive and the HDlive Flow silhouette rendering mode. These technologies provide fetal heart surface patterns by using a fixed virtual light source that propagates into the tissues, permitting a detailed reconstruction of the heart structures. In this scenario, ultrasound operators can freely select a better light source position to enhance the anatomical details of the fetal heart.

To present a prenatal diagnosis of diastrophic dysplasia in the second trimester of pregnancy using two- (2D) and three-dimensional (3D) ultrasonography. The mother was primigravida and aged 12 years. She underwent the first 2D obstetric ultrasound examination at 27 weeks, showing bilaterally upper and lower limb micromelia, thumb and hallux in bilateral abduction, bilateral talipes equinovarus; hyperlordosis of the lumbar spine, cervical, lumbar, and sacral scoliosis; cervical hyperkyphosis with the misalignment of cervical vertebrae, and straight clavicles.

Sirenomelia is a rare congenital malformation characterized by varying degrees of fusion of the lower extremities. It is commonly associated with severe urogenital and gastrointestinal malformations; however, the association of sirenomelia with anencephaly and rachischisis totalis is extremely rare. To our knowledge, the prenatal sonographic images of this association have not been previously published.

On the basis of 2-dimensional fetal echocardiographic findings, we investigated 4 different fetal vascular ring cases using spatiotemporal image correlation (STIC) combined with high-definition (HD) flow imaging. An in-depth 3-dimensional perspective of aortic arch branching (ie, the brachiocephalic arteries) was created by application of glass body and HDlive flow rendering algorithms (GE Healthcare, Zipf, Austria). Additionally, complete (U- or O-shaped) or incomplete (C-shaped) vascular rings were clearly differentiated in utero, and articulations around the trachea and esophagus were more easily imaged.
