“…3, Video clip 1), limb position and malformations and for investigation of the heart [39,40]. The actual clinical value of 3D-4D US is difficult to demonstrate but is certainly important for fetal anomalies [41], specifically the fetal brain and heart evaluation [42]. In gynecology, performing an ultrasound exam without coronal views can be considered malpractice but in obstetrics there are still no studies comparing 2D and 3D US in centers where practitioners are not 3D experts and thus, the routine use is still debated [43].…”

Ultrasonography. 2020 Aug 25. Epub ahead of print Diagnostic ultrasound (DUS) is, arguably, the most common technique used in obstetrical practice. From A mode, first described by Ian Donald for gynecology in the late 1950s, to B mode in the 1970s, real-time and gray-scale in the early 1980s, Doppler a little later, sophisticated color Doppler in the 1990s and three dimensional/four-dimensional ultrasound in the 2000s, DUS has not ceased to be closely associated with the practice of obstetrics. The latest innovation is the use of artificial intelligence which will, undoubtedly, take an increasing role in all aspects of our lives, including medicine and, specifically, obstetric ultrasound. In addition, in the future, new visualization methods may be developed, training methods expanded, and workflow and ergonomics improved.

“…Several 3D techniques have been described for the detection of cleft palate. 1,[32][33][34][35] The defect can be demonstrated in different modes: the multiplanar mode, tomographic mode, surface mode, and Omniview/VCR mode. 35 The defect is most readily demonstrated when the fetus is yawning and the oral cavity is filled with amniotic fluid (Fig.…”

Visualization of the fetal face with three-and four-dimensional (3D/4D) ultrasound is a unique experience for both, the parents-to-be and the operator. While the future parents are primarily interested in seeing the surface of the fetal face and facial movements, the operator uses the different display modes for a precise fetal malformation check. The multiplanar mode with a simultaneous display of the three perpendicular planes allows an accurate demonstration of a normal or an abnormal fetal profile. Even if an image of the fetal face is acquired in an oblique position, the stored volume can be rotated by the rotational controls in all three directions, until the face is seen precisely in the median plane. The different surface modes enable the operator to detect abnormal protuberant structures or surface defects, while the transparent mode (maximum mode) reveals ossification defects. During a targeted ultrasound examination of the fetal face, five different regions have to be assessed: the forehead, orbits and eyes, nose, mouth, and chin. With 3D ultrasound the following fetal anomalies can be detected: anomalies including the forehead (anencephaly, protuberant forehead, abnormal metopic suture, frontal encephalocele/meningocele), anomalies of the orbits and the eyes (orbital hypoplasia/microphthalmia, hypertelorism, hypotelorism,cataract, nasolacrimal cyst/dacryocystocele,cyclopia/proboscis), abnormalities of the nose (flat nose, absent nasal bone), abnormalities of the mouth (cleft lip/cleft palate, epignathus, macroglossia, chin anomaly (retrognathia/micrognathia). 3D ultrasonography allows a comprehensive evaluation of the fetal face with different display modes. In contrast to 2D ultrasound, 3D ultrasound enables a detailed demonstration of the soft tissue of the fetal face and thus contributes to a better understanding of the malformation by both the physician and the future parents.

“…This level of safety applies to 2D ultrasound as well as 3D ultrasound, which is inherently associated with particularly low emission values. Moreover, in the case of 3D ultrasound, the majority of the diagnostic process is performed using stored data [7]. During this process, the patient does not come in contact with the ultrasound transducer and does not even have to be present.…”

“…Diese Unbedenklichkeit betrifft sowohl die 2-dimensionale Abtastung als auchanders als oft dargestelltdie 3D-Sonografie, die verfahrensimmanent mit besonders geringen Emissionswerten einhergeht. Dazu kommt, dass bei der 3D-Sonografie der Großteil der Diagnostik an gespeicherten Volumina durchgeführt wird [7]. Dabei hat die Patientin weder Kontakt mit der Ultraschallsonde noch muss sie gar dabei noch anwesend sein.…”
