“…In der Fehlbildungsdiagnostik hat sich die 3D-/4D-Technologie als wertvolles additives Verfahren zur konventionellen 2D-Sonografie the fetal brain [7,19,23,25,26], can be precisely examined tomographically in the second and third trimesters. Heart defects as well as vascular anomalies can be visualized three-dimensionally using color Doppler [18,27,28]. 3 D neurosonography is playing an increasingly important role in the detection or exclusion of brain malformations since all planes can be precisely set and an exact comparison between the left and right brain hemispheres is also possible.…”

25 years of 3?D ultrasound in prenatal diagnosis represent an important milestone in recent ultrasound history. The initial stages of 3?D ultrasound were anything but easy. Although there were reports of initial experimental in-vitro ultrasound studies as early as the 1970s and 1980s 1 2, clinical use did not begin until the first commercial 3?D ultrasound unit (Combison 330, Kretztechnik Zipf, Austria) was introduced in 1989 (Fig.?1) 3 4. With this unit it became possible for the first time to produce so-called multiplanar (=?triplanar) images. This means that it was possible to display the three orthogonal two-dimensional image planes at the same time on the monitor (Fig.?2). Volume acquisition via a relatively large abdominal 3?D probe, which ? in contrast to the 2?D probe ? had to be held at a right angle to acquire a longitudinal scan, was unfamiliar (Fig.?3a, b). In contrast to the abdominal 3?D probe that acquired a pyramid-shaped volume with motor-controlled mechanical fan-shaped sweep of the scanning plane, a rotation method was selected for the volume acquisition with the 3?D vaginal probe for reasons of space. However, this had the disadvantage of central overlapping of all sectional planes resulting in limited image quality at the center (Fig.?3c, d). This disadvantage could not be eliminated until it became possible to perform a motor-controlled mechanical fan-shaped sweep of the imaging plane for volume acquisition with the 3?D vaginal probe. The introduction of the so-called surface mode made it possible to visualize surface images of the fetus and embryo with an abdominal as well as a vaginal 3?D probe. Due to the substantial processing power that this required, it initially (1992) took 6?hours to create one surface image with an external computer. Today a surface rendering of one image takes between 20 and 50 milliseconds depending on the volume. Parallel to this so-called internal or integrated system in which the complete 3?D unit is permanently integrated in the ultrasound unit and the 3?D probes are matched to the system (Fig.?4) 5, so-called external 3?D systems (e.?g. TomTec, Echotech, InViVo-System), in which acquisitions can be performed using any conventional 2?D probe, were also developed 5. An electromagnetic position sensor must simply be attached to the probe so that the transducer position and movements can be recorded on the basis of changes in the magnetic field (Fig.?4). After transfer of the individual 2?D images to a workstation, the images and their individual positions are assembled by a computer program to form a volume. The disadvantage of external systems is that the distances between the individual two-dimensional image planes are usually not identical due to the manual probe guidance, resulting in a lower volume quality, and that 4?D display is not possible 5. Due to the initial problems with 3?D ultrasound, many experienced 2?D ultrasound operators were initially skeptical of this new technique. Therefore, 3?D ultrasound was viewed as a difficult, inconvenient, and unn...

“…The dynamic real-time imaging makes ultrasound the modality of choice for characterization of a moving organ such as the heart. Some examples of the use of echocardiography are evaluation of cardiovascular anomalies in fetuses and newborns [139], assessment of aortic stenosis [140], evaluation of the function of the valves and examination of the flow and function after heart attacks. These examples are purely diagnostic applications without any kind of intervention associated, but ultrasound has also been used for guidance in cardiac surgery.…”

“…Among them, ultrasound has become the preferred method for diagnosing fetal congenital cardiovascular malformation because of its simple operation, low cost, no ionizing radiation, and real-time dynamics. [2,3] Ultrasound screening of fetal cardiovascular malformations in early pregnancy gradually plays a very important role in the regulation of pregnancy [4] . Combined with considerations such as maternal age, serum biochemistry, ultrasound abnormalities, and other ultrasound markers, ultrasound screening can identify most chromosomal abnormalities or abnormalities in the body.…”

Fetal cardiovascular malformations is widely focused and screened, but the accuracy of screening is not satisfactory. In this study, we compared the types of congenital heart malformation, accompanying diseases and fetal outcomes in the first and second trimesters of pregnancy to clarify the advantage of early screening.From January 2013 to June 2018, 230 fetuses were diagnosed with congenital heart malformations using ultrasound method in Qilu Hospital of Shandong University, and divided into 2 groups:the first trimester fetuses (group A) and the second trimester fetuses (group B). In addition, we collected and organized medical data of 347 cases diagnosed with congenital heart disease during 1998 to 2005 (group C). We compared the spectrum of congenital heart disease, associated comorbidities and outcome of fetuses diagnosed with congenital heart disease.There were differences in the types and incidence of cardiac malformations between the first and second trimesters of pregnancy. The number of cases of non-cardiac malformation, congenital heart disease with single ventricular circulation, fetal intrauterine death and premature pregnancy termination was significantly lower in the late stage (group A and group B) than that in the early stage (group C). More patients were screened for trisomy 21, 18, 13 syndromes and Turner syndrome in group A than group B (P <.001). More fetuses with a 22q11 deletion were screened in group B than group C.Early pregnancy screening using ultrasound diagnosis is very important for fetuses with congenital heart disease.
