Early Detection of Fetal Abnormality

Ritsuko K. Pooh¹

Abstract: After introduction of high-frequency vaginal transducer, transvaginal two-dimensional ultrasound has established a field of sonoembryology and most of the major fetal abnormalities have been detectable in the first trimester. Three-dimensional ultrasound adds an objective and comprehensive information to two-dimensional sonographic findings.

Recent development of three-dimensional (3D) high definition (HD) ultrasound has resulted in remarkable progress in visualization of early embryos and fetuses in sonoembryology. The new technology of HDlive assesses both structural and functional developments in the first trimester with greater reliably than two-dimensional (2D) ultrasound. The ability to visualize not only fetal face, hands, fingers, feet, and toes, but also amniotic membranes, is better with volumetric ultrasound than 2D ultrasound. In this article, detailed and comprehensive structures of normal and abnormal fetuses depicted by 3D HDlive are presented, including various faces of Down's syndrome and holoprosencephaly, as well as low-set ear and finger/toe abnormalities from the first trimester. Three-dimensional HDlive further "humanizes" the fetus, enables detailed observation of the fetal face in the first trimester as shown in this article, and reveals that a small fetus is not more a fetus but a "person" from the first trimester. There has been an immense acceleration in understanding of early human development. The anatomy and physiology of embryonic development is a field where medicine exerts greatest impact on early pregnancy at present, and it opens fascinating aspects of embryonic differentiation. Clinical assessment of those stages of growth relies heavily on 3D/four-dimensional (4D) HDlive, one of the most promising forms of noninvasive diagnostics and embryological phenomena, once matters for textbooks are now routinely recorded with outstanding clarity. New advances deserve the adjective "breathtaking", including 4D parallel study of the structural and functional early human development.

Both 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 HDlive technology. This technology is a novel ultrasound technique that improves the 3D/4D images. Furthermore, recent advanced 3D technology has produced exciting new applications of HDlive silhouette and HDlive flow. The algorithm of HDlive silhouette creates a gradient at organ boundaries where an abrupt change of the acoustic impedance exists within tissues. By HDlive silhouette mode, an inner cystic structure with fluid collection can be depicted through the outer surface structure of the body, and it can be appropriately named as ‘see-through fashion’. Close observation of small embryos and fetuses by advanced 3D technology in early gestation allows us to make diagnoses of various abnormalities. Novel imaging techniques are illustrated in the definition of normal embryonic anatomy as well as in the identification of many of congenital anomalies. Prenatal ultrasound has established sonoembryology and neurosonology, and advnanced HDlive and HDlive silhouette and flow imaging added further clinical significance to conventional 3D/4D imaging in those fields. They allow extending the detection of anatomical congenital anomalies to an earlier gestational age, and it is beyond description that noninvasive viewing of the embryo/fetus by all—inclusive ultrasound technology is definitely the first modality in a field of prenatal diagnosis, and help our goal of proper perinatal care and management.

Owing to prenatal ultrasound technology, there has been an immense acceleration in understanding of early human development. Recent advanced three-dimensional (3D) technology has produced exciting new applications of high-definition live (HDlive) silhouette and HDliveFlow imaging. By HDlive silhouette mode, an inner cystic structure with fluid collection can be depicted through the outer surface structure of the body and it can be appropriately named as see-through fashion’. Additionally, HDlive silhouette can depict hyperechoic structures, such as bones because skeletal system is demonstrated by ultrasound as conspicuously echogenic organs. HDliveFlow imaging adds more spatial resolution to conventional 3D ultrasound angiogram. HDliveFlow imaging demonstrates fine peripheral blood vessels, such as vascularity of the lung, brain and eyeballs. HDliveFlow combined with silhouette mode demonstrates the accurate location of vascularity inside organs. Simultaneous visualization of both structure and vascularity is quite comprehensive and may add further clinical information of vascularization. Thus, ‘see-through fashion’ imaging technology provides us comprehensive orientation and persuasive localization of inner morphological structure as well as of angiostructure inside the fetal organs. HDlive silhouette and flow imaging add further clinical significance to conventional three/four-dimensional (3D/4D) imaging in fields of sonoembryology and neurosonology, and may open up a new field of sono-ophthalmology. Owing to novel applications with clinical significance, fetal ultrasound is at present noninvasive, direct-viewing of the embryo/fetus, and all-inclusive technology, and is definitely the first modality of prenatal diagnosis with infinite potential.
