ABSTRACT Three-dimensional (3D) and four-dimensional (4D) ultrasound have improved our knowledge regarding the development of the embryo and fetus and of a great number of fetal anomalies. The great achievement in the field of 3D/4D ultrasound is high definition live (HDlive) technology and HDlive silhouette/flow technology. HDlive silhouette emphasizes the borderlines between organs with different echogenicity and it can be appropriately named as ‘see-through fashion’. However, it occasionally appears to demonstrate too many inner structures overlapping one another to understand their relations. The author has cut the volume dataset with a rectangle cube and rendered the cut slice with silhouette ultrasound and called as ‘thick-slice silhouette’. Normal brain image in the coronal cutting section by thick-slice silhouette imaging is the picture of the month. This method is useful to identify the inner structure of the organs.

ABSTRACT In the history of 3D/4D ultrasound technology, the great achievement was high definition (HD) live technology. This technology is a novel ultrasound technique that improves the 3D/4D images. HDlive ultrasound has resulted in remarkable progress in visualization of early embryos and fetuses and in the development of sonoembryology. HDlive uses an adjustable light source and software that calculates the propagation of light through surface structures in relation to the light direction. The virtual light source produces selective illumination, and the respective shadows are created by the structures where the light is reflected. This combination of light and shadows increases depth perception and produces remarkable images that are more natural than those obtained with classic three-dimensional (3D) ultrasound. The virtual light can be placed in the front, back, or lateral sides, where viewing is desired until the best image is achieved. A great advantage is that the soft can be applied to all images stored in the machine's memory. With HDlive ultrasound, both structural and functional developments can be assessed from early pregnancy more objectively and reliably and, indeed, the new technology has moved embryology from postmortem studies to the in vivo environment. Practically, in obstetrical ultrasound, HDlive could be used during all three trimesters of pregnancy. How to cite this article Pooh RK, Kurjak A.

ABSTRACT New technology in ultrasound imaging is allowing women to view more visually precise images of their fetuses than ever before. Maternal-fetal bonding describes the attachment interaction that forms between a mother and her unborn child. Ultrasound diagnosis modalities including two-dimensional (2D), three-dimensional (3D) and four-dimensional (4D) may create differences in the amount of maternal-fetal bonding, depending on the modality used. When relevant literature was reviewed on this topic, no significant difference between maternal-fetal bonding was found when comparing 2D vs 3D vs 4D ultrasound. However, certain measures such as a perceived feeling of closeness to the baby were higher with 3D and 4D ultrasounds as compared with 2D ultrasound. Further exploration is needed to ascertain whether different ultrasound modalities have an effect on maternal-fetal bonding in multigestational pregnancies, pregnancies in which there is fetal demise, and to overall examine the effects of using ultrasound for nonmedical ‘entertainment’ purposes by prospective mothers.

ABSTRACT Four-dimensional (4D) sonographic assessment of fetal facial expressions is considered to reflect normal and abnormal fetal neurological developments, and may be an important clue to predict the fetal brain function and well-being before and after birth. HDlive is a new surface-rendering mode, which uses an adjustable light source that facilitates the ability to create lighting and shadowing effects, thereby increasing depth perception. This technique facilitates extraordinarily realistic imaging of the fetal face, making it almost impossible to differentiate between actual photographs and HDlive images. In this article, we discuss recent topics regarding fetal facial expressions assessed by 4D ultrasound and HDlive, focusing on mouthing, sucking, yawning, blinking, tongue expulsion, scowling (pain/distress), and smiling. Moreover, we consider possibility of the existence of fetal emotion or awareness. How to cite this article Hata T, Kanenishi K, Hanaoka U, Marumo G.

ABSTRACT We present a series of images of different fetal intracranial, intrathoracic and intra-abdominal anomalies reconstructed using HDlive. It is a novel three-dimensional (3D) ultrasound modality that can provide the operator with naturally realistic features of any fetal anomalies. HDlive and its inversion mode are applied in several cases and two-dimensional (2D) sonographic images of different anomalies are also presented clearly to compare the advantages of HDlive in this article. This review focuses on the role of HDlive in the presence of such anomalies. HDlive should be a very useful aid in adjunct to other ultrasound modalities, specifically in cases that warrant detailed information. It can also be useful for the antenatal surveillance of anomalies, such as cystic lesions that may progress to complications. This innovative tool offers many promising advantages in clinical practice and future research on fetal anomalies. How to cite this article Cajusay-Velasco S, Hata T.

Abstract Significant advances have been made in accurate and reliable visualization of the cerebral circulation in normal and abnormal pregnancies. They provided the non-invasive studies of fetal cerebral angiogenesis and further development that filled some of the gaps made by neuroanatomical studies alone. The first breakthrough in the assessment of fetal circulation was development of Doppler system with purpose to obtain velocity waveforms. Continuing technical advances in Doppler ultrasound equipment, especially highly sensitive color flow imagining techniques have made it possible to study smaller anatomical parts of fetal circulation system including cerebral vascularization. Before examination of brain vascularity, anatomical vascular structure and development on the different appearance at each gestational age should be remembered as the basic knowledge. Since the development of the embryo is rapid and significant changes occur during even one week it is important to specify the stage of the embryo or fetus both by age (postmenstrual weeks and days) and by size (crownrump length (CRL) and biparietal diameter (BPD). Introduction of three-dimensional (3D) sonography and 3D power Doppler techniques have enabled visualization of intracranial vessels. 3D power Doppler assessment particularly adds useful information in the prenatal evaluation of normal brain development, vascular malformation and tumoral vascularity.

ABSTRACT Imaging techniques have continually evolved during the last few decades to improve diagnosis in obstetrics and gynecology. Developed more than 15 years ago, three-dimensional (3D) ultrasound has been widely used in clinical practice during the last decade, and its use continues to grow as researchers explore innovative new applications. High definition live (HDlive) ultrasound (US) is a novel ultrasound technology that improves both 3D and four-dimensional (4D) ultrasound images. This technology can mainly be used to study normal and pathologic embryonic and fetal development. HDlive could be important to perinatal research and could provide a better understanding of the development of the early embryo and fetus. Because of the natural pictures of the fetus that it provides, HDlive could be beneficial for increasing the fetal-maternal bonding, an important factor for healthy behavior during the pregnancy. In gynecology, HDlive could be useful in providing a better image of the adnexal pathology or coronal plane of the uterus. Although its advantages need to be further explored, in our opinion, HDlive is an innovative technique and a useful tool with applications both in obstetrics and gynecology.

ABSTRACT Presence or absence of the fetal corpus callosum plays an important role in prenatal counselling. With the recent development of 3D ultrasound technology, it is not only possible to demonstrate the corpus callosum precisely in the median plane but also to perform measurements of its different anatomical parts. This permits the diagnosis of hypoplasia and hyperplasia of the corpus callosum. Three-dimensional ultrasound enables even the unexperienced sonographer to take volumes of the fetal brain. Showing these volumes to experts in the field of neurosonography, corpus callosum pathologies can be detected via virtual examinations. Regarding all corpus callosum anomalies, hypo- and hyperplasia are the less reported corpus callosum abnormalities in the literature. Further investigations are necessary to predict the outcome of fetuses with corpus callosum pathologies. How to cite this article Pashaj S, Merz E. Abnormalities of the Corpus Callosum.

Multiparous Women

ABSTRACT Aim To evaluate the effect of parity on fetal behavior between primi- and multiparas. Materials and methods Fetal behavior was assesed by Kurjak's antenatal neurodevelopmental test (KANET) using four-dimensional (4D) ultrasound between 32 and 36 weeks of gestation. Forty-four primiparous and 61 multiparous women were studied. The total value of the KANET score and values of each parameter (8 parameters) were compared Results The total KANET score was normal in both groups except for in only one case in the multiparous group (total KANET score of 9), and there was no significant difference in the total KANET score. When individual KANET parameters were compared, we found a significant difference in only one fetal movement, isolated eye blinking, between fetuses of primiparas (median, 2; range, 0–2) and multiparas (median, 1; range, 0–2) (p < 0.040). No significant differences were noted in the other seven parameters. Conclusion Our results suggest that the level of relaxation of pregnant women may affect fetal behavior, particularly the rate of eye blinking. A relaxed state of primiparas may promote the maturation of the fetal brain, especially the central dopamine system function How to cite this article Hata T, Hanaoka U, AboEllail MAM, Uematsu R, Noguchi J, Kusaka T, Kurjak A.

Abstract Objective Microscopic surgery is currently considered the ‘gold standard’ for middle-ear, mastoid and lateral skull base surgery. The coronavirus disease 2019 pandemic has made microscopic surgery more challenging to perform. This work aimed to demonstrate the feasibility of the Vitom 3D system, which integrates a high-definition (4K) view and three-dimensional technology for ear surgery, within the context of the pandemic. Method Combined approach tympanoplasty and ossiculoplasty were performed for cholesteatoma using the Vitom 3D system exclusively. Results Surgery was performed successfully. The patient made a good recovery, with no evidence of residual disease at follow up. The compact system has excellent depth of field, magnification and colour. It enables ergonomic work, improved work flow, and is ideal for teaching and training. Conclusion The Vitom 3D system is considered a revolutionary alternative to microscope-assisted surgery, particularly in light of coronavirus disease 2019. It allows delivery of safe otological surgery, which may aid in continuing elective surgery.
